We were referred to Athletic Republic by my son’s team mate. There was a noticeable difference in his friends speed and agility on the soccer field. The classes are intense and I was unsure how my son would feel going so often but he loves it. The trainers really take the time to interact and invest in your kid. My son often mentions them making him laugh and joking around with him. When trainers/coaches connect with their athletes it really takes these kids capabilities to the next level. Soccer coaches should take note 😜 all that to say I highly recommend!

I hesitate to write this b/c I don't want it to become too crowded. :) We live in Sunset Hills and are willing to drive to Creve Coeur b/c this place is so awesome. My son started going there a little over 2 years ago and my daughters just started there. When they moved to Creve Coeur from Frontenac, we took a month long break to see if we could find something closer. There was absolute nothing that was even remotely close to being as good as Athletic Republic. They have the equipment needed to excel (no other place had high speed treadmills, let alone 4 of them), the absolute best trainers (not just some grumpy college kids looking to make a buck), and the price point is perfect (what other places are charging for unqualified trainers and worse equipment is laughable). The whole experience made me realize what a gem Athletic Republic really is. We simply love it!

My daughter has been attending trainings at Athletic Republic for almost 3 years now. To say its helped her is an understatement. She wanted to improve her speed and explosiveness and man, did she ever! They make these athletes better at their respective sports but also stronger physically and mentally and in turn their confidence will reach new heights! My daughter went from an average speed shooting guard to a fast, quick first step guard who can score at all 3 levels using the speed and agility shes built at AR. She will attend and play basketball at a D2 in 2026 and we definitely owe some thanks to AR!!!

Awesome place to train! The trainers are very knowledgable and friendly. There is a lot of available space and equipment for different types of training.

Athletic Republic does an incredible job of focusing on the core skills that improves a player's game. Core skills like Speed, Agility, Functional Strength and Mobility are the key ingredients to long term success. For the last year, I have taken both my daughters. As a soccer coach, this is the type of training that can take a team to the next level.

My daughter has seen tremendous growth by attending small group sessions at Athletic Republic. She has gotten fast, stronger, and more confident as an athlete. The trainers are personable and hardworking. Thank you!
