I have worked my way through just about every form of exercise and class out there, including personal training. These guys are the best. In just 8 weeks I saw a huge difference in strength, mobility, appearance, and injury rehab. I came to Opex to get help returning to exercise after a lengthy and pesky injury. Their approach to assessing your current state is very thorough. Every workout is tailored to you, and they are very attentive to their clients. I am hooked!

As a remote client, Mike and the Opex team is great. It's awesome to have a program customized to my fitness goals. I move quite a bit and it's great to have a consistent programming wherever I go. Also, Mike is very accommodating and tailors workouts to the equipment that I have available. I have seen great results in the short 6 months that I have been working with Mike and the Opex team.  I highly recommend Opex.

Austin O’Neal and I were passing through while traveling and decided to drop in. We loved the space! The gym was clean, the music was great, and the owner, Mike, was extremely helpful and friendly. We have dropped into a lot of gyms over the years and we know when we see a good one. OPEX St. Louis Central is just that! Thank you for letting us drop in! 😊

What an awesome gym full of friendly people. Dropping into a new place can be intimidating but Mike and the members were so welcoming.  I recommend checking this place out.

Opex St. Louis Central is a unique place. I really enjoy the workouts that Mike writes for me because they are challenging yet accomplishable and are customized to my preferences. I also love the community of the other members. Highly recommend for any skill level.
