I’ve tried a lot of workout classes in the area, and this studio is my favorite. All of the instructors I’ve had are great—super motivating without being over the top, and really good at giving clear cues and modifications.

What I love most is the balance of cardio and strength. The variety keeps things interesting, and I never feel like I’m stuck in a routine.

If you’re looking for a place that keeps you engaged, pushes you in the right ways, and has an awesome team running the show, this is it.

So happy to have hiit school in Willow Glen! Nick runs a great business and is a great / straight forward motivating trainer . Claire is really good too! Great music & it doesn’t get boring as it moves fast and each workout is different. The infra red sauna is a nice amenity they offer, too! 👏💪

I’ve done a lot of different fitness routines — CrossFit, Orange Theory, personal training — and HIIT school is by far the best combination of everything. Whether you’re looking for strength training or fat loss, it doesn’t matter — this place does it all. The best part is you get your workout done in 40-60 minutes and can feel great about the rest of your day!

There’s also cold and hot treatment on site for those who like the sauna and cold plunging.

Nick, Claire and AJ (the trainers) are all super knowledgeable, down to earth, and give excellent feedback. The workouts are diverse with a different focus each week — there’s something for everybody!

It seems like most who attend regularly have a success story so here’s mine: down 20 lbs, almost 10% body fat, all while increasing strength and muscle mass.

Try it out and I guarantee you’ll be hooked!

HIIT School has been a game changer for me. The workouts are so great and they change it up so often, you never do the same workout twice. It never gets boring. Trainer Nick is passionate about this program and his students and it shows every day.

Additionally, the other people that work out at HIIT are really welcoming. I have never been one to feel comfortable in a gym environment, but the sense of community at HIIT is totally different from other gyms I've gone to. The other people are of all ages and skill sets, but everyone supports each other and are very friendly.

Also I have never gone to a group class, that the members are all so friendly and encouraging to each other. Definitely no clicks! Everyone feels welcomed and valued as a member.

The Only School you won’t want to be a Dropout from! HIIT SCHOOL is just that, it’s an environment of learning and growing both physically and mentally. You will be immersed in all things fitness and how best to recover and allow your body and mind to seek out this place consistently. The Head Trainer takes your best interest to heart and approaches your personal journey with great energy and JOY! All the trainers are extremely talented and kind, they will guide and you provide you alternatives especially if you’re just starting out or returning from injury- HIIT school is for everyone! Oh and it’s FUN!! I’ve been a student for over a 1.5 years and am not only addicted to how great I feel but this amazing community. As a main attraction on Lincoln Ave HIIT School consistently participates in all the downtown WG festivities as well…. Oh and there’s an entire RECOVERY curriculum as well- infrared sauna, cool plunge, massages chairs and compression options! And if you’re still not convinced- they offer an entire free trial WEEK!!! Yes an entire WEEK!!! So try it out- you have nothing to lose and start demanding more for yourself! Hope to see you at the next class!!

I've been training at HIIT School for the past 2 years and I can honestly say I’m hooked. This isn’t your typical gym experience to do cardio and weights. The HIIT workouts combine cardio and strength training in a fresh and effective way. It’s intense, but there’s a clear focus behind every movement. Totally different that all those other gyms I have been to . What really stood out to me is how personalized the guidance is. When I told them about having some knee pain, the coaches showed me specific stretches to do before workouts, and that made all the difference. Turns out, it was just about prepping my body the right way. The HIIT program isn’t just for the younger crowd , but people over 50 can absolutely keep up and thrive here. I’m 59, and I’ve found the workouts to be totally doable, yet still challenging. :)
My main goal was maintaining mobility and improving balance and building strength and this place delivers!! I love it. HIIT School is addictive!!

If you want real results and a coach who genuinely cares, Nick at HIIT School is your guy. We’ve known him for years, and here’s the truth: he doesn’t just go through the motions he lives for his clients’ success.

Our daughter Emma started training with him after an injury, and the difference in her strength and confidence blew us away. But it’s not just about workouts. Nick’s the kind of person who makes you want to push harder because you can see how much he believes in you.

And here’s something most reviews don’t say: he’s changed how I think about my own work. We bounce ideas off each other, and his passion is so contagious it’s rubbed off on my business. That’s rare someone who doesn’t just train bodies but lifts people up in every way.

Bottom line? If you’re looking for fluff, go somewhere else. If you want a coach who’ll fight for your progress like it’s his own, HIIT School’s the only place we’d trust. Nick and his team? They’re the real deal.

Nick has been absolutely phenomenal! Our 13-year-old daughter, Emma, suffered an injury at the beginning of summer, and we were hesitant about jumping back into training. However, once she was cleared, we enrolled her in HIIT School’s youth strength and conditioning program.

In just a matter of weeks, the progress has been incredible—we can physically see the difference in Emma’s strength, confidence, and overall fitness. Nick’s approach is the perfect blend of expertise, encouragement, and inspiration. He creates a supportive environment that pushes kids to reach their potential while keeping it fun and engaging.

We also adore Sara and the entire HIIT School team—they truly care about their students and go above and beyond to ensure everyone succeeds.

If you’re looking for a program that delivers real results with coaches who genuinely invest in your child’s growth, HIIT School is the place to be. Nick and Sara, thank you for everything—you’ve made a lasting impact on Emma’s journey!

I've been a member of this gym for about 2 and half months and have been impressed with Coach Nick and the HIIT School community. I’ve been a member of MANY gyms over the past 20+ years and here a few things that stand out:

- One week trial with no pressure to join. I probably would not have tried this gym if not for the free trial. I anticipated a sales pitch but my trial week was a pleasant experience unlike many other gyms which can feel like walking into a used car dealership.
- Pricing transparency with no long term contract required, and no hidden/extra fees. Membership includes recovery therapies (cold plunge, infrared sauna, compression boots, massage chairs).
- Clean facility with well-maintained equipment, showers and towel service. Nick’s attention to detail makes the space inviting; I especially enjoy the variety of plants and heated toilet seats!
- Classes include intervals of strength and cardio and the programs change constantly so you will not be bored. There is also a yoga class on Sunday mornings that I highly recommend!
- Classes are held at a variety of times (as early as 5:20a), instructors are reliable and classes start on time! (These are priorities for me.) There are also open gym hours in addition to classes if you’d like to come work out on your own.
- Finally, Coach Nick is supportive, knowledgeable and has great energy. Some coaches use cookie cutter plans for everyone and make assumptions about goals (e.g. weight loss). I appreciate that Nick takes the time to get to know his members, ask questions, and offer modifications to accommodate personal goals, injuries, etc.

If you are looking for a new gym with a wonderful community in a super convenient location, I highly recommend giving the free trial week a shot!

Simply the best! I’ve been attending HIIT School for 5 months now, consistently doing 3 times a week, sometimes 4, plus yoga on Sundays. I can’t say enough good things about HIIT School.
Prior to joining, my only real exercise was a 15-minute brisk walk on my work breaks and the occasional weekend hike. My husband had joined a few months prior (he was already very active) and kept raving about it. He gave me a gentle nudge to give it a try with the 1 week free trial. I was pretty intimidated but decided to take the leap. After getting through that first workout and realizing I could actually do it, I kept going and signed up for the unlimited membership, which is the way to go!
Trainer Nick does all the work for you, you just have to show up. He is very strategic about tailoring the workouts to the students based on our progress, and no workout is ever the same. He and his coaches will help give you tips for proper form. He also changes up the music genre but it’s always on point and great to workout to. The community is so friendly and welcoming. On top of all this, there is amazing recovery amenities…I love the leg compressors. And that’s not all! The membership also includes free access to InBody scan…I did my first scan a month in and every month since and it is so validating to see those results of my hard work and progress. You also get a MyZone heart rate monitor when you join, and it’s a total game changer for accountability and pushing myself during workouts.
Oh and how could I forget, on weekends there’s sometimes homemade cold brew—thank you Sarah! :)
HIIT School has had such a positive impact on my life, not just physically but maybe even more so mentally. If you’ve read this far, what are you waiting for? Come join and get to school! :)

I’ve been attending HIIT School for a year now, and I—I LOVE it. Nick is an incredible trainer who brings out the best in everyone. He’s always encouraging us to push harder, get stronger, and stay consistent. Every workout is thoughtfully designed, hitting every major muscle group while keeping things fresh and challenging. I never leave class without feeling accomplished and energized.

The studio is amazing—bright, welcoming, and fully equipped with state-of-the-art equipment that’s seamlessly integrated into each session. What I most appreciate about HIIT school is the holistic approach. It’s not just about intense workouts; there’s a real emphasis on recovery and overall well-being. The sauna and compression boots have made a huge difference in my recovery, and I’ve learned so much about how to take care of my body, which has actually boosted my performance over time.

On top of all that, I’ve made amazing new friends here. The supportive, positive, and driven community is what keeps me coming back week after week. If you’re thinking about starting or leveling up your fitness journey, join HIIT School—it will be the best decision you make this year!

I've been working out forever and have tried a lot of different programs to stay in shape. From personal trainers, instructor-led gym classes, Barry's Bootcamp +++, but NOTHING compares to HIIT School! I was lucky to discover HIIT School at Google, where I work, and participated in the onsite workouts there and absolutely loved it! When I found out that Nick opened up an actual studio in Willow Glen - I quit my Barry's membership and signed up. It has been an integral part of my life ever since and I cannot say enough wonderful things about the intentionality and variety of the different exercises that Nick puts together each week. There is never a dull moment and your body is constantly being challenged in various ways to achieve overall fitness...and it is so much FUN!!! Good vibes and great community - not to mention all of the additional complimentary perks that are part of the membership! They have the best recovery equipment available - including an infrared sauna, cold plunge, massage chairs, leg recovery boots and Theraguns. The facility is BEAUTIFUL and clean.

Stop Thinking About It—Just Sign Up!

I’ve been with Hiit School for five months now, and it’s been a total game-changer. I started with the twice-a-week package for about three months until I felt ready to level up—and now I’m on the unlimited plan and loving it! I’m going about 4-5 days a week, and the convenience is unbeatable.

The facility is super clean and well-maintained, with top-notch machines, great amenities, and an awesome, tight-knit community. It’s located right in the heart of downtown Willow Glen, and the fact that they have their own parking lot is a huge bonus—no circling the block looking for a spot.

Coach Nick is the best—motivating, supportive, and always pushing you to be your strongest. He’ll make sure you’re lifting the right amount of weight and getting the most out of each workout.

If you’re even thinking about joining, take advantage of their one-week free pass. It’s the perfect way to try out the classes, explore the amenities, and see if it’s the right fit for you. And if you sign up afterward, you get a free heart monitor, which syncs to an app so you can track your heart rate, calories burned, and overall progress. It’s an awesome way to stay motivated and accountable.

Seriously—stop thinking about it. Just sign up. You won’t regret it!

It’s been a year since I joined HIIT School, and I’m proud to say I’ve completed over 100 classes! Looking back, I’m amazed at how far I’ve come. I feel stronger now than ever before.

For years, I avoided the gym. The machines were intimidating, the crowd overwhelming, and the distance inconvenient. I made so many excuses that I convinced myself I hated working out.

Then, I found HIIT. At first, it was tough, but trainer Nick was there every step of the way — supporting, guiding, and pushing me to do more than I thought possible. He understands each person’s fitness level and helps them grow at their own pace.

I strongly recommend HIIT School! Nick and Sarah are so welcoming, caring, and attentive! Naturally, all of the students that come here are as well!

If you’ve ever felt lost in your fitness journey, this is the place to start!

Come join us, you won’t regret it!

Can’t say enough good things about HIIT School. The classes are always challenging and the range of high-end workout equipment allows for people of all fitness levels to be pushed. Coach Nick does a great job mixing up the curriculum and instructing the class why we’re doing particular movements and exercises while also demonstrating how to correctly do each movement to maximize your workout.

The facility is pristine, upon walking in you get the sense that it’s just been sanitized and that cleanliness is a priority. Plenty of recovery options are available for post-workout (sauna, cold plunge, massage chairs) and there are also plenty of showers and bathrooms if you need to head straight to work after.

Stretch sessions and yoga classes have recently been added as well as an InBody for body composition analysis. This place has everything you need. Highly recommended!

Five Stars for HIIT School in Willow Glen!

I’ve been hitting HIIT School for six months now, and let me tell you—this place is the real deal. Nick, the owner and trainer, is a force of nature. His presence on the floor isn’t just a nice-to-have; it’s the backbone of the gym’s culture. He’s genuinely invested in every member’s success, and his thoughtful approach to programming means every workout feels like part of a bigger plan—not just a random sweat session. I never leave without feeling like I gave it my all.

The community here is something special. It’s inclusive and supportive—no egos, just people putting in the work. Nick’s wife, Sarah, adds a beautiful touch to the space with her warm, inviting energy. She’s never too busy to say a quick hello or offer a cup of her incredible homemade cold brew (seriously, it’s worth the visit alone).

With the gym just a minute from my house and parking always a breeze, it couldn’t be more convenient. Whether you’re a seasoned athlete or a total newbie, I couldn’t recommend HIIT School enough. This is where you go if you want a killer workout and a community that makes you want to keep coming back.

It’s so hard to find intelligent HIIT workouts with great peeps, vibes, and playlists. For me search is over! The HIIT school in Willow Glenn has it all. Thoughtful instructors, intelligent metrics, regular workout changes to keep you on your toes (no pun!) And a salty crowd of serious students for the social side of the equation. Great perks too… had a tasty coldbrew as a surprise at my last session on Saturday!

Thanks Team HIIT 💪🏼😝💪🏼

As someone who has done Crossfit, Personal training and F45 for 15 years, I have to say HIIT School is the most well rounded fitness program for the average joe or ex athlete.. you only need to go three days a week... No really.

The programming is well thought out and hits the whole body every time, no crazy exercises like Crossfit and helps keep you and ready for life. I smoke all my friends on the climb up hill when mountain biking now!

What Nick has put together here is a world class facility, he has the same equipment pro teams use, cold plunge and a sauna to top it off. For what you pay he delivers a great value, program and I can't really say anything bad.

HIIT School with Coach Nick has been an absolute game-changer for me! In just two months, I lost 1 inch off my waist and dropped my body fat from 14% to 10% measured on top of the line In-body scale available at the gym at no cost. The workouts are intense, well-structured, and incredibly effective. Coach Nick pushes you to your limits while keeping things fun and motivating. If you're serious about getting leaner, stronger, and fitter, this is the place to be. Highly recommend!
And I have to mention the all recovery tools available like suna, cold tank and legs compression.

HIIT School really is the BEST! Had no experience in the gym, and didn’t really know where to start. Tried a personal trainer, but it wasn’t sustainable and was hard to keep the motivation. Found HIIT School through a friend…game changer completely! First and foremost, Nick and the trainers he hires are really the best. With his HIIT workouts, I never need to think about what to do or worry about getting in good work; and the creativity keeps it dynamic and well rounded. I get all the benefits of a personal trainer, and some, as he is constantly keeping an eye on form and taking the time to explain and teach the what/how of everything we do. The gym itself has all top notch equipment, it’s spotless clean, well maintained, and the schedule is built to have a time to fit any schedule. Then there’s recovery equipment and all kinds of other equipment and resources to help track progress and guide you on your fitness journey. On top of all that, the community of regulars is awesome - everyone is supportive/motivating and I’ve made some really cool friends (esp w the fun events they coordinate outside of the program). I never thought group fitness would be my thing, but HIIT School has become a big part of my life and been so good for me, both physically and mentally. Almost a year in, I feel better than I’ve ever felt and seen awesome physical results.

Can’t say enough good things, come sign up!

I’ve been looking for a way to challenge myself and improve my fitness, and HIIT School has definitely delivered! The workouts are high-intensity, engaging, and tailored to different fitness levels, which makes it easy to get started and keep progressing. The instructors are motivating and offer modifications when needed, ensuring that everyone can push themselves.

One of the best features of HIIT School is their recovery station. After a workout, it’s amazing to have access to a cold plunge, sauna, massage chairs, boot compression, and more. It’s the perfect way to help your body recover and recharge for the next session.

I also love that when you walk into HIIT School, it doesn’t feel like a typical gym that’s trying to sell you protein or supplements. The focus is truly on your health and wellbeing. The workouts speak for themselves, and it’s clear the gym cares about its members and their fitness journey. It’s a great place where you feel supported, encouraged, and truly valued.

Overall, HIIT School has been a game-changer for me, and I highly recommend it to anyone looking to level up their fitness routine in a supportive and results-driven environment!

I've been training for years with personal trainers and small fitness classes, but I never got the results I truly wanted until I joined HIIT School. This is hands down the best gym I've ever been a part of. In just about 6 months, I've lost nearly 40 pounds.

Trainer Nick is fantastic; he keeps the training program both fun and fresh, changing it up every two days so you never get bored. Thanks to this dynamic approach, I've not only seen a significant weight loss but also impressive muscle growth. I feel like I'm in the best shape I've been since college! The only downside to this gym is that I need to buy new clothes because they all are too baggy on me now.

I highly recommend HIIT School to anyone looking to transform their fitness. The sauna, cold plunge, massage chairs, and the leg compression make the gym even more worth it.

Most importantly, any intimidation you may be feeling walking into a new gym is immediately taken away by the friendly environment. The trainers, as well as the veteran “students” are extremely welcoming and helpful. Everyone loves the community they’ve built and it shines through the moment you walk in the door.
I’ve been attending classes and utilizing the recovery equipment for 8 months and still look forward to my next time in the gym. I have gained strength and general fitness, but most importantly by feeling the motivation to attend classes regularly, in a community type environment, I’ve gained overall well-being. I can’t recommend this place enough. Get to class!

When I relocated to the Bay Area, I was in search of a gym that could provide me with everything I needed-- state of the art of equipment, access to recovery, and most important: top of the line trainers. I hit the jackpot when I stumbled upon HIIT School. Trainers Nick and Kyle are extremely knowledgeable, patient, and invested in every member's fitness goals. They go out of their way to provide feedback, ensure that everyone's form is correct, and create diverse classes that push our bodies to new limits every time. I also really enjoy access to open gym, as it gives me time to implement everything that Nick and Kyle teach us during classes.

I've done a lot of fitness routines over the years, and most of them start off great, but over time get boring or easy or both as you and your body get used to the workouts. Not HIIT School. Nick and Kyle and the team keep it fun and challenging by constantly changing things up, and by setting different goals for students with different capabilities and levels of fitness. They made sure I had appropriate exercises a long time back when I was recovering from an injury, yet still continually challenge me even when I'm in great shape and feeling my best.

The workouts and the community they've created have kept me coming back to their programs for years already, and I expect the same in the future.

Been going to this gym since it opened. I used to train Crossfit for the last several years, and the barbell style from Crossfit has given me muscle imbalance issues that have become painful.  HIIT style workouts are intense, if not more, than Crossfit.  However, at HIIT School, their programming emphasizes on body balance workouts, just as much as intensity. Another huge amenity is the recovery programing with massage chairs, cold tub, and sauna all within the same facility.  My lower back and right knee pain have become increasingly minimal. I only wish I had joined their Mobile HIIT School program years ago.

The trainer I have worked with the most is Kyle, and I would definitely recommend him to everyone! He is professional, friendly and patient! In both group class and 1-1 training, he keeps focus on everyone all the time, corrects ppl’s form, and pushes to the limit (in a nice way of course).

I can’t say enough good things about HIIT School. The workout, trainers, and community are what sets this fitness program apart. It’s been my most consistent workout for the past 5+ years. The trainers have coached me and provided nutrition advice through various life changes, including getting ready for my wedding, staying active through 2 pregnancies, and gaining back my strength postpartum. When the pandemic hit, the HIIT School community remained strong, and continued to be a source of regularity, comfort and friendship in a difficult and uncertain time.

I new them by name because my colleagues where obsessed with them. Now I know why. Kyle and Nick are the reason one keeps coming back for more.

I've been taking HIIT School classes with Trainer Kyle since 2019 and keep coming back because his workouts are engaging, challenging, and fun! I especially appreciate how he modifies exercises to support my on-going knee injury and kindly keeps me accountable when I lose focus. Thanks to Kyle's guidance, I've gotten stronger and maintained a consistent workout habit, which has been life-changing (truly). If you're looking for a supportive and challenging workout environment, HIIT School with Kyle is the perfect place!

Perfect fitness solution for busy parents seeking an effective and time-efficient fitness program!

As a busy working-parent, finding time to prioritize my fitness was a struggle. I knew I had found something special when I stepped into HIIT School!

It has been an absolute game-changer for me since day one. My fitness journey kicked off with incredibly supportive and knowledgeable trainers, led by the dynamic duo of Nick and Kyle at the Willow Glen campus. They both are friendly and are truly dedicated to your fitness success. They have an infectious energy, creating an elevated vibe where every workout feels like a high-energy fitness party, complete with pumping music and personalized guidance to keep you motivated and engaged.

The school opened an entirely new world for me with its revolutionary HIIT program. Whether you are a beginner or an advanced athlete, their carefully crafted workouts target every aspect of fitness, from strength and performance to mobility training. Each week is designed differently with purpose and intention to change the workouts to maximize your output with real results that you can feel and see. In just two months, I’ve witnessed transformations in my physique, strength, and overall wellness. The real results speak for themselves with my increased energy, elevated mood, and a newfound confidence in my fitness.

HIIT School understands the challenges of balancing work, family, and fitness. With classes offered at various times throughout the week, I can easily fit in a session whenever I can that suits my busy schedule. Plus the modern boutique vibe and top-notch equipment and unique amenities make every visit feel like a retreat for me.

HIIT School isn’t just a gym - it’s a second home and family that prioritizes your health and fitness goals, and provides a comfortable and conducive environment to obtain them! If you’re ready to transform your body and make every minute count in the gym, give them a shot!

I couldn’t be any happier with my decision with HIIT. They leveled up my fitness game while making the most of my precious time with real returns and fitness fundamentals you’ll learn along the way with them!

I haven't been to the physical facility but I take HIIT School classes twice a week at 7am at a corporate facility. Kyle and his team keep our crowd active all the time and encouraged. The workout is different every time (and in most cases, changes every 60 seconds). Kyle is very good at jumping in with modifications to help people dealing with injuries or other conditions, and he also provides the occasional nudge on form which helps me feel he's paying attention to ensure we get the full benefit without injuring ourselves. Some years back I was a 5+ day a week Crossfitter. But HIIT School has a higher ratio of aerobic to lifting exercise than Crossfit, and is tolerant of a just-twice-a-week schedule which honestly fits my life more reasonably now. I always feel motivated to come and work out with HIIT School and enjoy my 7-8am slot. It's definitely "worth it". Thanks Kyle and team.

I’ve been working out at this gym for the past few months and I really love it. The coaches are wonderful and do a good job explaining the type of workouts we’re going to do, demonstrating them, and explaining why/how the different exercises have been paired together to help our health. I’d highly recommend. Before this, I hadn’t worked out in months but the program and community help keep me motivated to come back!

Can’t thank HIIT enough. I’m anti cult gym (aka OTF aka F45 aka bay club aka FORMA) This place is home. There is community. There is structure. There is accountability. It took me about 6 weeks to get accustomed. I was not out of shape, but I wasn’t in shape. The workouts are hard but had you told me where I was today back in December, I wouldn’t have believed you. Take those photos you’re embarrassed about. Join HIIT. Prove those photos wrong. Be confident.

Highly recommended! HIIT School offers a well-crafted, effective, and time-efficient program that provides more than just physical benefits – it's a source of immense inspiration. With its solid foundation, I experienced significant increases in physical strength and achieved full-body toning. Thanks to its support in building my fitness foundation, I not only completed my first half-marathon but also conquered a full marathon in 2023. Starting my fitness journey with HIIT School in 2022 was truly rewarding!

Fun and engaging workout with awesome instructors. Nick and Kyle create a great vibe during the workouts. New and clean facility with a variety of equipment (a.k.a HIIT stations). Lot of slots in the morning, noon and evening to suit busy schedules.

They have interesting offers going on. If the first class feels challenging, do not give up. Try at-least one more before deciding. You will likely be hooked for years :) I have been with Nick, Kyle and AJ before they even opened the school. So can vouch for these amazing folks.

HIIT School is one of the best gyms I’ve worked out in. Coach Nick and Kyle have created a strong community here that motivates everyone and makes anyone feel welcome. The facilities are first class from the equipment on the floor to all the recovery tools that are at your disposal (Normatecs, Hypevolt guns, cold plunge, sauna, massage chairs). The programming and class structure are set up to make you successful and make quick progress whether you’re a newbie or professional athlete.

Highly recommend! I've been attending HIIT School for three months now. The staff have been very attentive to my needs on my fitness journey. They are excellent at providing guidance and motivation to keep me moving! I finally found a gym that allows me the flexibility with a wide variety of class times and the modern equipment that is helping me become stronger. All the equipment is new and regardless of your fitness level, will challenge you to your limits. The focus is on total body fitness from stretching to proper form and recovery. I can't speak highly enough of the staff who always go out of their way to ensure I'm meeting my goals. Plenty of parking and a community feel will keep me coming back for more.

I've been a member at HIIT School for the past eight weeks, and I can confidently say that it's been an unparalleled fitness journey. This gym is not just a place to work out; it's an experience that goes beyond expectations.

First and foremost, the gym boasts top-end equipment that caters to all fitness levels. The variety and quality of the machines make every session effective and enjoyable. The cleanliness and organization of the workout area demonstrate a commitment to maintaining a premium fitness environment.

One of the standout features of HIIT School is the team of trainers led by Nick, the owner. Nick's expertise as a trainer is evident, and his passion for fitness is contagious. He not only provides guidance during classes but also takes a genuine interest in each member's progress. It's clear that he is committed to helping everyone achieve their fitness goals.

The other trainers, particularly Kyle, are equally impressive. Their knowledge and skill level are apparent, and they create an atmosphere that encourages personal growth and improvement.

I've been participating in classes twice a week, and the results speak for themselves. My VO2 Max has noticeably increased, and I've achieved a level of muscle definition that I hadn't thought possible in such a short time. The trainers' personalized attention to form and technique has played a significant role in these positive changes.

Beyond the workout sessions, HIIT School offers a high-end facility that caters to recovery and overall well-being. The cold plunge, sauna, and other recovery equipment are invaluable additions to the gym experience. These amenities provide a perfect balance to the intense workouts, ensuring that members can optimize their recovery and prevent injuries.

HIIT School is more than just a gym; it's a haven for fitness enthusiasts who are serious about achieving their goals. The combination of top-notch equipment, expert trainers, and luxurious recovery amenities makes it a standout in the fitness community. My personal journey at HIIT School has been transformative, and I wholeheartedly recommend it to anyone looking for a comprehensive and rewarding fitness experience.

Fun, clean, and inclusive classes. You choose how challenging it has to be for you, lead by an amazing instructor. Nick will make you feel like the bada$$ you are & bring out the inner beast. Count on a great workout in an hour including a warm up, brief for safe movement & ongoing coaching throughout. Then take a shower, jump in the cold plunge, enjoy compression therapy or a massage.
This is where you need to go.

I have been doing corporate classes from HIIT School for years but this gym is next level! The experience is super high end. From the latest equipment to the recovery services, HIIT School caters more to your own journey rather than just being a mill cranking out classes. All the trainers are all solid experts with a no shame mentality. They truly and honestly care about your own fitness journey. This is the best place. I even make time to travel here from San Francisco! That’s commitment.

I love work out classes. You name it, I've probably tried it. I've been going to HIIT School for a few weeks now and I can honestly say that its different from all the other group workout classes. How? They incorporate 5 types of cardio in every session; and the strength training portion of the workout includes a various combination of TRX, kettlebell, dumbbell, slam balls, and resistance machines. The trainers do an awesome job at explaining how to use the machines and will often give me feedback on my form to make sure I am getting the most out of my workout. If you are looking for a fast paced and fun work out - I highly recommend checking them out!

This is a top notch facility. It’s all you ever wanted in a performance and recovery fitness center. From the high tech equipment that few other places provide, to the sauna and cold immersion that is vital for recovering from one workout to the next. There is far more here than any other standard fitness classes. I’m glad to be a part of it.
