I have been working out with Arielle for 5 months. Her ability to listen to my needs and her knowledge of how to meet those needs physically is amazing. She has me motivated to get up every day and go train with her. I’m 54 years old and this was the best decision I have made to get myself back in shape and feeling more confident.

I started partner (me and a friend together) workout sessions at Crossfit Thunderbolt with Arielle Luis about 6 months ago along with some video workouts I can do at home and I've never felt this strong and energetic! I'm addicted! Arielle is very knowledgeable, comfortable and makes it fun! She helped ease me into better shape than I've been in a long time! She's so good at switching up workouts, setting goals, having us reach our full potential and correcting our forms to prevent injuries! Love it and I can't say enough to recommend Arielle and her CrossFit Thunderbolt gym!

I’ve been working with Coach Ariélle Luis/her digital programming and I have really enjoyed the process. I’m challenged to meet my goals, encouraged by my coach, and Ariélle has quick response time on my lifts to help effectively correct my form. I am excited to keep grinding and see goals be met!

I’ve been going to CrossFit for several years, but my form and mobility have always been lacking. I took a class with Arielle and it really taught me to dial back on speed and focus on the form. She provided great guidance and tips on how to improve Olympic lifts. I would highly suggest taking some be of her classes!

I love CrossFit Thunderbolt. It’s a welcoming, positive & encouraging community run by knowledgable, caring and motivating coaches. There are always new challenges, activities and trainings. I recently attended the snatch clinic taught by Coach Arielle. It was well taught- breaking down the movement into bite sized pieces. I walked away with a better movement and tips and tricks to take with me to help in the future.
Overall would highly recommend.

CrossFit Thunderbolt is my home away from home. Not only have I gotten stronger and fitter, but I have met the most supportive people and made good friends here.
All the coaches are wonderful and so helpful. Coach Arielle had an amazing Snatch Clinic this weekend that really helped with my technique. I can’t wait for the next one! If you want to be part of a caring community, get a great workout and learn a ton along the way-this is the gym for you.

If you're looking for a box that cares about their members, this is the place. Any gym can have the equipment, but VERY few have coaches that go above and beyond for their members.

One thing I’ve really enjoyed… Ariélle’s snatch clinic! We got to see and breakdown the snatch step by step. I can clearly see the results of great instruction. I can’t wait for more clinics to come. What’s a great investment!!

It took a friend a very long time to convince me to walk through the doors at CrossFit Thunderbolt 5 years ago. I’m glad she didn’t give up. Sometimes walking through the door is the hardest part but once you do you will never turn back! You will find a supportive, inclusive community who will meet you where you are at in your fitness journey.
In addition to CrossFit, Thunderbolt also offers hybrid fitness training for events like Hyrox and DEKA, and specialty classes such as barbell and Olympic weightlifting.
I recently attended a snatch clinic with Coach Arielle and was incredibly impressed with the attention to detail and feedback she was able to give each athlete.
When you join Thunderbolt you are truly joining a family who will support and care about you. It is the best part of my day!

Everyone that steps foot in this gym would agree that the coaches, owners, and members of CrossFit Thunderbolt are the most welcoming, friendly, and knowledgeable people in the fitness industry. It is a great space that provides training across all disciplines, including OCR, Hyrox, and olympic lifting, in addition to CrossFit. Thunderbolt offers numerous classes throughout the day, making the gym extremely accessible to all members 7 days a week. The gym is very well-equipped. Besides the basic necessities of a typical CrossFit WOD(rigs, barbells, dumbbells, boxes, etc) Thunderbolt hosts a large turf cutout for sled work, and plenty of cardio equipment, including air runners, ski ergs, bikes and rowers.

One of my favorite places to be. There are so many wonderful people here that are caring and supportive. Not to mention, the best coaches. They help so much with individual goals. It’s truly a great environment. There should be an option for 6 stars! ⭐️ Thank you Thunderbolt for all you do!

I had a great experience here as a drop in on their Rowathon event raising money for the children's organ transplant association. This is a huge box, but they were so welcoming that my partner and I instantly felt like part of the family. So many people came up to introduce themselves and offer support, and there is so much positive energy here!

It is true, I suppose, that you can get a decent workout at most any gym. And you will get great workouts here, but Crossfit Thunderbolt is a 5-star experience because you get so much more than just a workout:
— Coaches who are knowledgable, friendly, and attentive. They are committed to knowing each student in every class so they can ensure that you get the best workout possible that day, making adjustments for any limitations you have.

—Community that is truly top notch. Welcoming and kind, everyone cheers on everyone else. We share about our lives and joke around, but also definitely get after it in the workouts. In the end, you are only really competing against yourself. Still, it is also true that there can be a bit of competitive fire—but only in a fun, healthy way.

—Classes that vary in style and ages. I go to Crossfit and Open Gym. But there are also kids classes, teen classes, OCR, barbell, and more. The facility is expansive, inviting, and variable.

You may have heard any number of wild and crazy rumors about Crossfit being unsafe, or ridiculously, impossibly difficult, or only for young, insanely-fit folks. There may be places where that is the case, but it absolutely isn’t true at Crossfit Thunderbolt. Yes, some of the workouts are incredibly challenging—and there are some movements I just cannot do. However, every single movement done in every single class is adaptable. Coaches work with you to scale any exercise into a version you can do.

I’ve been a member at a lot of gyms over the decades, but I’ve never had a better experience than I do at Crossfit Thunderbolt. You should give it a try.

I first stepped through the doors of CrossFit Thunderbolt to do a Hyrox event to support a friend.
As I walked in I noticed the facility was very big! As I’ve been a CrossFit athlete for over a decade now, bigger CrossFit gyms appeal to me.
Right away I was connected with one of the owners who immediately welcomed us to all of the fun family friendly outings. This is all before my husband and I even attended any classes, we got to meet coaches and members at a Kane Cougars game and at the quarries in Lemont rock climbing!

One of the First things I noticed is how strong the female coaches are, not just physically but mentally. With each class I took the the female coaches made sure to talk with me and not only make me feel I was welcome but let me know! So do the male coaches but I’ve been to my fair share of gyms and this is not always the case with the female coaches. It was so refreshing they were so eager to engage with me! ♥️

On top of the welcoming and great community, they also make safety a priority. Coaches make sure to know what is going on in your life so they can best tailor the work out to fit you and your needs for that day. Whether it’s an injury your facing or maybe just a long day.

Along with CrossFit & Junior CrossFit classes they also run a great OCR class(hosted by a high energy Humble BA), a solid Olympic weightlifting class (hosted by amazing accredited weightlifters), & Brazilian jujitsu (Hosted by an officer)!
All under 1 roof, for any skill level!

If your thinking about giving it a try just do it ! You won’t regret !

♥️Also a special thank you to every single coach there for giving me something great to look forward to in my day ♥️

Was only here for about two months and unfortunately I had to move due to work. I wish I would of found this CrossFit gym sooner. The coaches are great! Owners Scott and Molly were always very welcoming and friendly. Coach Christine was awesome and always very helpful and you can tell she loves what she does. Facility is in great condition as well as the equipment. I highly recommend anyone to check this place out. Hope to one day come back. Thanks guys!

Strong As Oak (SAO), an awesome obstacle course racing group, meets 3 times per week at the Crossfit Thunderbolt gym. SAO is led by 2 all-star coaches, George "Yogi" Grandolfo and Jeff Wolschlag.

The group meets for about 75 minutes at the following times:
6:30 pm on Tuesdays
7:30 am on Saturdays
10:00 am on Sundays

Tuesdays are generally obstacle course racing. Saturdays are more focused on competition training. Sundays are more flexible - a coach-led class or open gym.

Any fitness level welcomed! The group is very supportive of one another. The 1st class is FREE!

Before visiting any Crossfit gym I was very intimidated , and thought I would feel out of shape and awkward. As soon as I walked into the gym I realized how wrong I was! This gym is so welcoming, I never once felt out of place. If you are on the fence about crossfit I highly recommend trying this gym!

what can i say about this place? it's incredible.

the coaches: the coaches are welcoming and very approachable. they're incredibly good at finding what works for your level of fitness and then helping you build from there. there's no pressure to move to higher weights if you're not ready.

the members: even more importantly, the athletes are all very welcoming. there's a real sense of community and everyone is truly supportive of each other. one of things that makes this place great is that i've never seen the stereotypical gym "meathead" that thinks they're better than everyone else. to be honest, i don't think they'd even let someone like that join.

the building: holy moly... it's huge! you could park a 747 in this place. ok, so it's not quite that enormous. but, it is big and a very nice facility. lots of space to spread out.

the equipment: plenty of equipment to meet your every need.

the workouts: variety, variety, variety. i never joined a typical gym because i felt like i wouldn't get enough variety and eventually get bored left to my own devices. i've been going to Crossfit Thunderbolt for a little more than 1.5 years and i have never been bored. the workouts have always been challenging and the coaches will help you scale the workout if you can't do particular movements. (i've got a bad knee so i get to row instead of run. yay?)

the classes: class size is capped at 12 people. i feel like this gives the coaches the ability to give individual attention as needed while running the class.

the air/assault bikes: i hate these things. they are the bane of my existence. but hey... who uses legs to walk anyway? (note: this is my personal opinion. if you like these things, more power to you.)

overall rating: 12 out of 10, would highly recommend.

Dropped in while visiting family in the area. What a great box! Huge and clean facility with very approachable coaches and athletes. I accidentally dropped in to an open gym without reviewing the schedule. However, the coach offered to help me build a workout if I'd prefer. I decided to join up with two other athletes training at the time and joined their workout. The whole gym made me feel like home. I will certainly be back.

I love crossfit Thunderbolt. It is a great community and they get results. I have dropped 50 pounds went from a size 38 to a size 32 pants size. The coaches are wonderful they help with everything from doing a healthier diet to programming challenging workouts that get results. If you are looking to loose weight drop in. If you are looking to improve your cardio health drop in. If you are looking for a community that cares about you and your progress drop in. You will have fun and get a workout in. Yes coaches I said fun.
