I can’t say enough great things about Kaizen, and the amazing community that Chris has built. I have been working with Jen for almost 2 years. She’s an incredible trainer who is truly dedicated to her work and her clients success. Her energy, passion, and commitment to training are unmatched. She inspires me every single day to show up as the best version of myself. Working with her has greatly improved both my physical and mental health. If you’re looking for someone who genuinely cares and will push you to reach your goals, Jen is your girl!

First off I would like to say that I came into this experience very nervous and guarded, being it’s been a good 8 years since I’ve truly worked out. Chris, the owner, was very welcoming and supportive from our first
phone conversation and through the first assessment. After being part of this gym for only a few short weeks, I noticed changes in myself I haven’t seen in a while. Coach Darien has been the perfect balance of patience, yet pushing me to my limits. If you’re looking to make healthy changes while having fun at the same time with a group of awesome people, definitely check out Kaizen.

A Hidden Gem for Fitness Enthusiasts!

Training at Kaizen with Chris has been a game-changer. The moment you step through the door, you know this isn’t your average gym—it’s more like your own private fitness clubhouse. No crowds, no chaos—just clean, sleek equipment and a vibe so good you’ll want to work out just for the playlist.

What truly sets this place apart is Chris, himself. He’s not just knowledgeable—he’s passionate, patient, and incredibly motivating. Every session is tailored to your goals, whether you're rehabbing an injury, training for a sport, or just trying to get healthier. His attention to form and technique ensures you’re progressing safely and effectively.

My only point of contention is that he doesn’t know how to count! Seriously—your “last three reps” somehow turn into seven more.

So if you’re serious about your fitness and want a supportive, expert-led experience, this is the place to be.

I waited three months before writing this so I could give an honest review — and I can confidently say that joining Kaizen was one of the best decisions I’ve ever made. It hasn’t just improved my physical health; Kaizen has had a huge impact on my mental and emotional well-being too.

When you come to Kaizen, you’re not just coming for a great workout — you’re joining a community. It doesn’t matter how much you can lift or where you are in your fitness journey; there will ALWAYS be someone cheering you on. And trust me, the workouts are tough — I’ll complain through every single one — but the best part is, you get to complain together. ✨

I’ve found myself doing things I never thought I could, both in and out of the gym. Kaizen has given me the confidence to show up even on the days I feel like I have nothing left to give — and somehow, I always leave feeling 100%.

Special shoutout to Mr. Christopher David and Jen for “tricking” me into joining and for continuing to walk alongside me on this journey.

Working with Jen one-on-one has truly been a game-changer. I’ve had personal trainers in the past, but nothing compares to this experience. From day one, she brought an unmatched level of energy, care, and expertise that made every session feel purposeful and empowering. Jen designs customized workouts, brings all the vibes, and knows exactly how to push you—gently but effectively—toward your goals.
Before joining Kaizen, I didn’t always feel connected to the gym or confident in the process. But over the past six months, my entire perspective has shifted. Kaizen makes fitness feel fun and intentional. From community events to partnering with other spaces to create the vibe tribe (a run club), Kaizen builds more than just strength—it creates lasting memories. It’s something I actually look forward to (well… most days lol) - a place of consistency, growth, and support.
Kaizen is a small but mighty environment filled with like-minded people who motivate and uplift one another. It’s not just about working out—it’s about showing up for yourself and for each other.
The impact goes far beyond physical transformation. From Jen, to the owner Chris, to Donny, Lauren, Michelle, and former coach Celine—each trainer has played a meaningful role in this journey. Their passion, presence, and commitment to helping people thrive is felt in every session.
Big shoutout to Ms. Sherry and Jay too—I appreciate y’all!
I’m so grateful to be part of this community. 1% better every day.

Kaizen is the perfect gym if you're looking for a hard workout packed into one powerful hour, a small and engaged community, and trainers who push you beyond your limits. I had left my old martial arts gym and was looking for a place that would push me to my fitness goals without making me feeling like I'm just another credit card. I literally never knew I could lift the amount of weight that I do now. From day one, I felt welcomed. Chris and Jen are the best! Highly recommend Kaizen!!

I joined the Kaizen Fitness Health and Wellness community on March 14, and it instantly felt like home. Everyone is so kind, welcoming, and encouraging. It’s the kind of place where people truly lift each other up. I had never worked with a trainer before, but joining Kaizen has been one of the best decisions I’ve made for myself.

From my very first session, Jen made a huge impact on me. She’s not only an amazing trainer, but also a genuine, inspiring person who pushes me beyond what I thought I was capable of - and I love that about her. In just a month, I’ve already noticed changes in myself, both physically and mentally, and I’m so excited to continue this journey with her.

The other trainers are just as kind, motivating, and passionate about helping people reach their goals. Every workout leaves me feeling good, lighter, and more positive. Being surrounded by people chasing their goals, with trainers who truly care, makes every session 10/10 amazing!

As I reflect on my journey, I realize that October 5th, 2024, marked a pivotal moment in my life. Weighing 248lbs, I felt lost and disconnected from my body. The pain in my knees was a constant reminder that I needed to make a change. But it wasn't until I walked into Kazier Fitness that I felt a sense of hope and renewal. The warm and welcoming environment, combined with the expertise and professionalism of the trainers, made me feel like I was in good hands. Celine, my trainer, was instrumental in helping me find my footing. Her patience, kindness, and guidance helped me build confidence and develop a love for fitness.Also all the other trainers are amazing people there JEN & Lauren The community at Kazier Fitness is truly special, and I feel grateful to be a part of it. Chris, the owner, is a visionary leader who has created a space that is both supportive and challenging. I've lost 20lbs, and my knee problems have disappeared. But more importantly, I've gained a newfound appreciation for life and a sense of purpose. I highly recommend Kazier Fitness to anyone who is looking for a transformative experience.

Kaizen is perfect for people who are trying to get stronger and fit. Lauren helps pinpoint weak areas and train them to be stronger. She is also very educated when it comes macroing food and extremely thoughtful. When I told her about my high cholesterol she did so much research on my behalf. She is the best and her body is worth motivation.

Kaizen has been my favorite gym I have ever joined. I joined at a time where I hadn’t worked out in a few years, so through hardwork and determination, they helped me get back into shape, but more importantly, helped me get back my confidence. Now I am able to instill fitness back into my daily life and go to the gym, run a few miles with ease. I also genuinely appreciate the way they went about it too. I’ve been to a few gyms where it feels like you’re working out with a drill sergeant. Not at kaizen, it seems like the trainers at Kaizen have been able to master the ability to be kind, compassionate with pushing their clients beyond their capabilities but not so much that it makes it unbearable. It’s quite an art.

Thanks Kaizen!

She has taught me so much, has pushed me to do things I never thought I could do and I am so much stronger already a couple of months later. Their semi-private classes are so fun and they always give individual attention, which I really appreciate. Seriously every trainer here is awesome.

I go at least three days a week and the vibes are always great. I look forward to going every single week! I can't imagine not being a part of this gym.

When I first joined Kaizen, I was searching for a facility that would provide the structure and tools I needed to achieve my fitness goals. I couldn’t be happier with my decision! The classes are both challenging and engaging, and the community is incredibly supportive and uplifting.

The staff here is truly exceptional—they push you to be your best self while always being personable, motivating, and accommodating. Every trainer takes the time to ensure you’re set up for success, and their encouragement makes all the difference.

I’m so glad I found Kaizen, and I’m excited to continue not only reaching but exceeding the fitness goals I’ve set for myself. Highly recommend to anyone looking for a welcoming and results-driven environment!

The best gym ever! I would highly recommend this gym to anyone, regardless of age. Moreover, I’d recommend it even if you’ve had surgery or suffered a serious injury and are looking for a place to recover.

I’ve been a member of Kaizen for 2 months now, doing both semi-private and private training. When I joined, I had a very stiff knee (from an injury in 2019) and a bad ankle (from a serious injury in early 2023, which required surgery if it didn’t improve). Additionally, over the past 5 years, I had gained some weight and lived a fairly sedentary lifestyle. I also have flat feet (low arches), which caused knee pain (among other issues) due to improper tracking of my patella. Needless to say, my fitness was in poor shape when I joined.

Since joining Kaizen, I’ve been working on my knee and ankle with Donny. It’s been just over two months, and I already feel a huge improvement. My knee, ankle, and legs feel fantastic. I can do exercises I haven’t been able to do in a while—like squats and lunges with ease. I can now hike trails rated as “moderate” to “difficult” on AllTrails. I’m no longer afraid to pick things up from the floor or tie my shoelaces without sitting down on a chair. Donny’s approach is methodical, and he puts a lot of effort into getting your fitness up to speed. He takes a personal interest in your health and is committed to helping you achieve your fitness goals. Plus, he’s a fun and positive guy to work with—especially on those mornings when you’re gearing up for a challenging session or a workday.

Last but not least, the semi-private sessions are fantastic. I’ve trained with Chris, Jenn, and Celine, and they are all wonderful, patient trainers. In a class of a maximum of around 8 people, they still manage to give individual attention, ensuring your form is correct, keeping you motivated, and making sure you get the most out of the sessions.

I've been working out at Kaizen Fitness since October 9,2024, and I'm thrilled with the results so far! My personal trainer, Celine Ezik, is phenomenal. She brings so much energy and focus to every session, making sure each 1-on-1 workout is impactful. Even when I've struggled with certain movements or showed up late, she adjust seamlessly, maximizing every minute we have. Her dedication and punctuality make Mr look forward to each session!
My workouts begin at 5 a.m., 3x a week, but I often find myself coming in for more. The positive vibe and sense of community at Kaizen Fitness are.truly addictive! It's a 17 minute drive, but it's absolutely worth it. Besides my 1-on-1, I also attend the 5 a.m Fitness classes with Jennifer, who's just as amazing. She leads each session with such enthusiasm that my initial goal of 3x a week workouts quickly doubled!
The entire staff and fellow members are friendly and supportive, making Kaizen Fitness feel like a second home. I couldn't recommend it enough for anyone looking for a motivating and fun environment to reach their Fitness goals!

I rarely leave reviews, but this time, I have to. I've had memberships to different gyms but never stick to it because they never kept me motivated. So I saw Kaizen Fitness online doing a promo for a fitness challenge and joined. This place is amazing. The trainers are top notch-they know their stuff, have great energy, and treat everyone like a friend, which i love. It's such a positive place, and they have classes that can meet everyone's schedule. I don't dread going to work out because you feel like you're with a group of friends, so it takes the "ugh" out when thinking about going to the gym. This is a special fitness studio, and I would recommend it to anyone to give them a try.

To call this “just a gym” is an insult. I’ve been coming here over the past 11 months and in this time have lost over 50 pounds gained self confidence and joined a family. Because when you come in through those doors that’s what you become here is part of a bigger family. The coaches really take the time of day to work with you to help you achieve whatever it is you are striving for be it in a group or private lesson. Quite honestly my personal trainer, Jen, has literally transformed me physically and mentally which was far beyond what I was expecting when coming here. She has taught me the virtue of Kai Zen which means little changes over time which is exactly what happened little by little my mind and body progressed everyday to where it is now. This virtue is something I use now in my day to day life. So to surmise when you sign up here you’re signing up to more than just a gym. You’re signing up for a family who will support and guide to whatever goals you have :) if I could give Kai Zen 10 stars I would!

I recently completed the 8 week challenge where I attended Kaizen about 4x a week and this challenge in particular provided a nutritional plan. I started this challenge feeling exhausted and lazy both physically and emotionally. I can proudly say that I am down 4% body fat, 6lbs lighter and best of all I feel energized and motivated to keep striving to reach my best self! The trainers at Kaizen design challenging workouts that pushed me to perform at a level I did not think was possible. Big shout out to trainers Jen, Chris and Kim for being excellent at what they do and always pushing us to challenge ourselves even when we are close to giving up. I cannot recommend Kaizen enough!

Joining the Kaizen family has proven to be an immensely rewarding decision. Initially apprehensive due to my lack of experience in strength training, Kaizen team made me feel like home. Donny and Kim diligently refined my form; and Jennifer and Chris consistently pushed me beyond my limits. Their collective expertise and dedication have not only helped me achieve my personal goals but also fostered a sense of belonging and motivation within the classes. My husband and I successfully completed the 8-week transformation challenge and could not be more happier with our progress. I now eagerly anticipate each 6 a.m. class and look forward to embracing the challenge. For those seeking a transformative journey, both physically and mentally, I wholeheartedly endorse Kaizen as the ideal destination.

I want to start of with this review by saying how happy I am to be part of this gym. I’ve never been a gym girlie but coming here has kept me accountable and motivated. A big part of my confidence has to do with the best trainer a girl can have my girl Jen. She has the most amazing energy and vibe ever. It can be 6am or 7pm her energy level she brings is unmatched. I have lost 43LB with the help of a good diet but also working out. Having Jen as my trainer means having someone who celebrates with you all your accomplishments whether is inside the gym or out. I have become a better me and I don’t have words to ever thank her for helping me get to my goals. I would 100% recommend anyone to come to this gym. Everyone makes you feel welcomed and a huge shout to Chris because he is a great owner!

Great gym and empowering atmosphere - I highly recommend! My membership is for semi-private classes (meaning the classes are limited to a max of 10 guest per session), which gives the trainer the opportunity to get to know you one on one and focus on correcting each person’s form. All 4 trainers are well knowledgeable and approachable. I also love the community here…we cheer each other on and take notice when someone doesn’t show up for a long period of time.

I’ve met Chris a few years back as my trainer, He helped me a lot with not only with my physical fitness but also my mental wellbeing. I’m very happy he got his own gym because I believe he is there to really help people who are not only struggling but also striving to be better even if they’re at their best already. Not only is he giving help to his clients but I see him help his co workers and co trainers. I attended classes with them and I felt assured and it’s safe to say he got them on the same page to just help people. All I can say is, I wish the schedule could have been more accommodating especially to night shift workers like me. But then again, Seeing KaiZen provide the best training in discipline and fun at the same time makes fitness achieved in a very high level. I appreciate you guys for your warm hospitality since from the start. I love your auras, your mottos and messages everyday. That’s why I continue to do the work. I’m almost 20 pounds down and it’s not done because we ain’t stopping. Goodluck and best regards to all! Chris you the man bro! Keep it up and I’ll see you guys soon!

I recently moved to Hackensack and was on a mission to find a place that could help me get in shape without making it feel like a struggle. Let me tell you, I hit the jackpot with Kaizen! The progress I've made in two months is mind blowing, and I can't help but rave about the awesome trainers there.

The team at Kaizen are like a bunch of superheroes in gym gear. They're not just doing a job; they genuinely care about your journey. My trainer, Jen, is an absolute gem. She pushed me past all my mental and physical roadblocks. Now I'm lifting weights like it's no big deal. 💪🏼🥰

But it's not just about the workouts. Chris, another star at Kaizen, has been my meal plan guru. He's setup an amazing food plan system that makes eating right second nature. He has even helped swap out bad ingredients from my everyday meals to fit my goals.

The Kaizen crew has made this fitness thing feel like a casual, everyday part of life. If you're on the lookout for a friendly and effective place to get in shape, Kaizen is the way to go.

I recently visited a friend in New Jersey and followed him to a drop in session at Kaizen. Travelling and staying fit is an arduous task but my friend assured me it would be worth it. I have major gym anxiety and from the moment I stepped in I felt so welcomed! It truly felt like a judgement free zone which immediately made me feel at ease. The gym itself was clean, well lit, with updated equipment and a variety of machines. Plus, a gym with such great attention to detail to have hair ties, deodorant spray and hygiene products in their bathrooms... sign me up!

Now on to my friend's personal trainer Jen... what a gem! She has such a presence to her! She is respectful, powerful, encouraging, super personable and pleasant and will push you to be better in a way that makes you want to go back! She is also very knowledgeable about the body and nutrition and shares that knowledge to provide a tailored experience for you. 10/10.

I hope my friend knows that a session with Jen is now a permanent fixture on my New Jersey calender!

I have been at Kaizen for 2 months now and it has been nothing short of amazing. The space is clean, modern and open which from the outset is inviting and not intimidating. An assessment was made of me, and I was assigned to be trained by Jennifer Reyes- she is absolutely excellent. I know this should be a review of the gym, but I HAVE to speak about my trainer.

Jenn: unmatched professionalism, and highly motivational. There aren’t enough good words to describe. I have so much fun working out, that even when it gets hard I am still excited to go. She sees my weaknesses and works on them. She has been helping me uncover what my goals are, and we have been working to achieve them. She encouraged and motivated me to join group classes to help diversify my workout routine. Her personal training does not end there - she helps me track my nutrition, and checks on how well I have been sleeping, literally the whole package. She is also ALWAYS reading, and so you know she is not only up to date, but also using evidence based methods to help her clients achieve the best.

Even though Jenn is my personal trainer, all the staff warmly greet and check in whenever I am in the gym. I am extremely happy to have found this new family and I highly, wholeheartedly, and unreservedly recommend them.

Kaizen focuses on personal training, rather than a typical gym structure. Their trainers helped me get back into high intensity workouts, but there are many other members with differing workouts goals. Every trainer is very friendly and will work with you to tailor workouts to meet your goals, while respecting any physical limitations.

Kaizen is a great option whether you are looking to build muscle, lose weight, or be generally healthier, but need some extra guidance or accountability in your workouts

I recently completed Kaizen’s 8-week Transformation Challenge and what a great experience it was! Not only did I lose 4% body fat during that short amount of time, but I also became so much stronger in the process! The trainers were incredible! I attended most of the 5am classes with Jen—what a way to kick off my mornings. She found ways to motivate me—even while half asleep! I also had the pleasure of taking some classes with Kim—she sure knew how to push me— I was stronger than I thought! She challenged me to believe that I had the power to push thru heavier weights! Chris had dynamic energy during his power hour sessions that I attended. And Donny really helped me with mobility recommendations to do at home. Overall- they are a great group of trainers! In addition to the outstanding staff, their app made it simple to sign up for classes. It also had great meal options. While I didn’t utilize the meal tracking portion of the app much, there’s certainly value to it if used consistently. Kaizen gets a 👍🏽 from me! Check them out—they won’t disappoint!

I’m 67 years old and I thought I would never be able to work hard again but….
Thanks to Donny Drummond I know anything is possible!! Spoil yourself and get a training plan from one of the many great staff members working at this friendly, comfortable gym! The daytime belongs to us 😁. PS I’ve been here for a year and a half lost 20lbs and maintained my weight without changing my diet 👍😎

Just finished Kaizen's 8 week challenge and I could not be happier. Their guidance and attention was nothing short from perfect. They listened to my concerns and adjusted the meal plans to my wants and needs to help me reach my goal at the end. The easy to follow recipes were delicious and got me out of my comfort zone (I was even able to get my picky eating kid to eat some veggies!). The semi private classes challenged me to exceed my limits and having the support from my trainers and team mates made every step of the way so much better. I look forward to continuing with Kaizen and reaching my fitness goals.

I’ve been going to Kaizen over six months now and I have nothing but great things to say about it. Chris (personal trainer) is phenomenal- he always pushes me to my limit in addition to tailoring our workouts to my needs. I injured my knee back in August and with the help of Chris and Donny- my knee injury is fully recovered. I would recommend KaiZen to anyone that’s looking for an intimate training experience. All the staff members are friendly and personable. The gym has all the basic equipments that you need to get the job done and is always kept clean.

Been training with Donny with 4 plus years. He's helped me overcome a very tough low back injury, and get back to training athletically again 💪🏾

Guillermo deserves all the stars!! What a wonderful human. He's been training me this year after I had my one year old. I hadn't been back in the gym since her birth and I'd never worked with a personal trainer before. Guillermo is such a sweetheart who will still push you to reveal your hidden potential. I'd come straight from work to the gym dog tired and somehow, G still would find a way to make me still give 💯 during our sessions. He's gifted in being able to balance structure and professionalism with compassion and kindness. I never feel judged or overlooked when I work with him. He's totally focused with the hawk eye on my form and posture and whenever I workout on my own, I still follow his guidance. I lucked up having him as my trainer. He's just awesome!

I can’t recommend this place enough! I started going in July because I was stuck in a rut with my workout routine and wanted to try something new. Not even 2 months later, I am down 12 pounds and already seeing so much muscle definition. I take the 6am group classes with Jen and Chris - they are both amazing people and really keep you motivated the whole time. There is also an awesome community of people who attend the classes - and everyone has different levels of fitness/skills but the classes are built for everyone to succeed. I wish I found Kai Zen sooner!

A great spot to go at your desired pace. They recently expanded their class schedule, which makes training easier for people with flexible schedules. Crossing my fingers for a yoga supplement soon!

It is so rare to walk into a gym and feel like you have been friends or family with everyone. They make you feel comfortable IMMEDIATELY.
The training is exactly what I need, not only showing you what to do, but correcting your form. I sweat non-stop in these classes (I pretend it is fat leaving my body). I love that they are small in size, so it feels very personal. Everyone giving each other a fist bump at the end of class feels like mission accomplished.
HIGHLY RECOMMEND!

I am so glad to have found this place. I have been training with Jenn since I started 3 months ago and seeing results. Love her energy each and every time we meet and love how she pushes me to the limit. Chris is also amazing, kind and funny. I have yet to try one of his classes but from what I've seen he pushes your limits too. So whether you sign up for personal training or just attend the classes, you will get results.

Chris has built an amazing program!! My husband and I were both in a fitness rut and joined Kaizen a few months ago. Chris and his team have completely transformed us, mentally and physically. They are very accommodating when it comes to scheduling, and you can tell how much they truly care about your success. I have been working with Jen, and she is absolutely phenomenal. I’ve worked with personal trainers in the past, but all of them paled in comparison to Jen! She pushes you to levels you didn’t know you could reach, while at the same time she is meticulous about teaching proper form. I could feel that all her slight adjustments were minimizing any joint strain while also ensuring that I get maximal results from the movements. I cannot recommend Kaizen and Jen more highly- give them a chance and you will not be disappointed!!

Been attending semi-private training sessions at Kaizen Fitness with Chris and Jen for over 2 months now. From the very first session it’s been nothing short of great. I’ve always had issues with staying consistent with working out but I look forward to the training sessions at Kaizen. They will push you and motivate you to give it your all to where you are feeling more confident with each workout and feel like you’re a step closer to your fitness goals!

Very happy I found Kaizen!

I love training here! I started coming earlier this year after not lifting consistently for all of 2022. The trainers have gotten me so much stronger!! I have taken Jen and Chris’s class most often and I find them very educational and fun. It is a very welcoming atmosphere. Always feel great leaving here - you should definitely check it out if you’re looking for a place to lift in a group setting or get personal training in the Hackensack area.

Truly a great place to be. The trainers here are not only knowledgable about the ins and outs of fitness, but they are also amazing people who want the best for you. Regardless of what your fitness goal is, Kaizen will have you making strides in that direction from day one. Very grateful to be a part of this atmosphere that brings out the best in you mentally and physically. They will welcome you with open arms and seek out what works best for you. Couldn't be happier with making the decision to join at Kaizen, I hope you do as well!

I was visiting Hackensack for a week. Jen invited me to check out the gym, as they had a one week free promotion. Even though I was only there for a week, Chris and his group welcomed me in. Their semi private classes are fun and challenging (good music to boot!). Chris provided modifications that were individualized. I would definitely recommend to anyone who lives in the area!

This place is just a gem. Since I started with Chris, I’m down 30 lbs, and feeling great. Donny is a wonder with recovery work, and loosening muscles that you didn’t even know were impeding your fitness progress. And Brie and Jen? Don’t fall asleep on these ladies, because they will kick your butt with their workouts. Everyone here is fun, friendly, and highly knowledgeable, and even though your body gets put through it’s paces, your mind feels refreshed and invigorated. I recommend this gym to everyone who wants to develop and keep a healthy lifestyle.

I have been training with Donny at Kaizen for a few months, now, and I can not say enough about how much Donny has helped me change how I feel, how I move, and how I approach training. He observes you as a whole unit and adjusts how he trains you on what he sees. He has a wealth of knowledge and is always learning more. I would recommend him as a trainer no matter where you are on your training journey.

Awesome! I did a group fitness class that was so much fun and really challenging! I work out a lot and was so happy with the knowledge of the trainers, the great music, and clean facility with great equipment. I came back for a personal training session with Bri that was fantastic! She gave me amazing tips!! I also just did a recovery session with Donny that was excellent! He helped alleviate chronic back tightness I had that was actually caused by tight muscles in my legs/hips - I had no idea that was the cause! He was so helpful!

I've had such an amazing experience working out with Bri at Keizen. I started with a free consultation which i found she went above and beyond, the consultation itself was not just measurements and a scale like most places, it also consisted of exercises that allowed Bri to help me with my goals. I've never enjoyed having a personal trainer as much as i enjoyed going to Bri. She kept me motivated, gave me homework to do at home on the days i did not go train, she followed up with and always had a plan ready for me. I am so happy i found this Fitness Center. If you are looking for a personal trainer all the trainers at Kaizen are professional, knowledgeable, motivating, and friendly. I never felt embarrassed or ashamed to try new work outs, l always felt comfortable because everybody is so friendly. This place is a GEM. I HIGHLY RECOMMEND IT.

By far the best fitness facility I’ve ever visited and became a member of. For someone that loathes fitness and exercise, the staff makes my experience enjoyable each time I train. My personal trainer is Brianna. She’s knowledgeable, punctual, pleasant, and always challenges me beyond what I thought I could do. I appreciate the fact that members are there by appointment only as I typically hate crowded gyms. On a busy day, I’ll be there with 2-3 other ppl training with their coaches as well. This gives me the freedom to feel more comfortable and puts my mind at ease as we all consider social distancing. I’d recommend Kaizen to anyone that is interested in true growth and working with people that are invested in you.

Kai-Zen is a very clean and well managed training facility. The trainers are attentive and are personally invested in helping me reach my fitness goals. The owner Chris has put a lot of time in to helping me learn to physically work out on a consistent basis, mentally stay committed and he has also helped me clean up my eating. I enjoy coming to the training facility knowing I am learning something new each time as well as having fun!
