“I absolutely love being a member of Eureka Crossfit. The workouts are challenging but scalable for all fitness levels, and the coaches genuinely care about helping you improve safely and consistently. The class schedule offers so much flexibility, which makes it easy to fit workouts into a busy mom and business-owner schedule. The accountability, encouragement, and community are what keep me coming back. Everyone is welcoming, supportive, and pushes you to be your best. If you’re looking for great coaching, convenient class times, and a gym where people actually know your name, this is it!”
“The Saturday morning bootcamp sessions are intense but fun. Everyone encourages each other without making it feel competitive. I struggled keeping up during my first class, and the coach adjusted a few exercises so I wouldn’t feel left behind. That kind of attention keeps people motivated to return.”

“For someone that has lived a fairly sedentary lifestyle this place can seem intimidating. I have also tried numerous workouts, dance videos, fitness influencers, etc and I have been able to be the most consistent with Burn. It's something about the community that helps hold you accountable but in a positive and sincere way. And it's not just for seasoned fit folks, they have modifications for every exercise and work with your individual strengths so you never feel like you can't do it. Trust me, I still struggle to get up in the morning to go but I just do it and before you know it we are tackling the finisher and I am feeling so good about myself.”
“OTF Chesterfield is not only a place to go for a great workout, but it’s a place to go for great community! Andy and his whole team are fun, warm, inviting, and motivating!”

“Patron for almost 2 years, the newer Nutrition App is awesome and tracks by scanning your product sku and then does the math for you! You can add your recipes and get suggestions based on your individual nutritional and fitness goals built together with staff. The staff are great, offering coaching and gentle reminders when I drop off. Best thing I have learned, setbacks are not really setbacks when you are doing well with exercise and nutrition setback becomes minor pause and your body can can handle normal indulgence. Thank you FIT BODY!”

“Great gym!!!! Nick helped me troubleshoot some membership issues with ease. Our family is part of the late night workout gang so up until this evening I hadn’t been in during “staffed” hours.
This evening I tried out one of the shred classes and it was amazing!!! Nick and Robyn are so helpful and down to earth. The other people participating in the class were just as awesome!!! I will definitely be back for more classes!!! Thank you guys!!!!”
“American Muscle Gym has been a game changer for me and my husband! I’m currently training for a bodybuilding bikini competition, and this gym has everything we need to stay on track. The equipment is top-notch—lots of free weights, machines, and enough space to train without feeling crowded.
The atmosphere is amazing—everyone here is serious about their goals but still friendly and supportive. Big shout-out to the owner and staff for creating such a motivating environment and always being helpful whenever we have questions! Their knowledge and support truly make a difference when you’re pushing yourself to the next level.
If you’re looking for a gym that motivates you to work harder and reach your goals, American Muscle Gym is the perfect place!”

that alone says it all! The workouts vary daily and are great! Karla is the perfect coach and the coaches under her are really great as well. Like I said - 14 YEARS!!!”
“I never write Google reviews, but my experience with Against Gravity has been so wonderful that I couldn't help but do so. I started training here at my mom's recommendation; she signed me up for training in an effort to help me recover from an eating disorder and heal my relationship with my body. Coming in, I was starving, very low-energy, and terribly unconfident in the gym. Ryan and Tommy both knew this, and they worked with me to develop a strength training routine and a nutrition plan over the course of a summer. They were extremely supportive on both my good and bad days, and they work hard to provide a positive experience tailored to the individual goals of each client. I've since fallen in love with lifting, and my mindset is as healthy and strong as ever. Of course, I've put in a lot of mental and physical work myself, but my experience at Against Gravity was so overwhelmingly positive and encouraging; I couldn't have turned my mindset around without them. If you’re struggling with your confidence, looking to better yourself, or want to develop your physical and mental discipline, I implore you to pay Against Gravity a visit. I owe much of my success in recovery to them (and my mom). I cannot thank this team enough!”

“My secret gym. I used to think these smaller gyms just weren't worth it. But most gyms are very crowded nowadays and it's nice to have a small spot where I don't feel like someone is directly in my space.
My main criticism is the lack of equipment, but hey, that goes with the territory of being a small gym that's generally not overcrowded. 24 hour access is great to have.
Edit: Working out here in the summer is rough. AC seems pretty low. Feels like it's 80 degrees.”

No towels !!! ........ dispensers with brown paper are provided. We're accustomed to the blues and whites. Altogether great place; clean & welcoming.”

“Chesterfield location is spacious and well-equipped with nearly everything you could need. They’ve recently added hydromassage and cryotherapy chairs upstairs, plus a cold plunge in the pool area. The pool sauna is excellent and maintains high heat consistently, and the steam room is great when it’s operational. However, the sauna in the men’s locker room runs noticeably cooler.
The biggest drawback is the limited hours. At around $200 per month, this facility really should offer 24-hour access - or at the very least extend hours until midnight.
Some areas could use updating. The locker rooms and showers feel dated compared to other locations like Frontenac, and the equipment could use refreshment.
Additionally, the guest policy is unnecessarily restrictive. The same friend can only visit once every 60 days, which feels unreasonable given the premium membership cost. If members are paying around $200 per month, they should have more flexibility with guest privileges.”
“Dotties is a true Gym only location. Open 24 hours so it's great if you have a busy schedule. it looks small from the outside but Dottie has done a great job organizing the inside and it has everything you need for a great workout”
