- Sam Williams
My wife and I dropped in from out of town for a quick workout with our family. This has to be one of the greatest environments to workout and grow in that we have ever seen. Brock, his family, his team, and everyone else do everything they can to make you feel welcomed and comfortable. Brock loves this gym and the people inside it very well - would recommend to anyone!
- Bent Creek Bouquets
Arnold CrossFit is one of the most friendly gyms I have ever dropped in at. I was immediately greeted by the owner, Brock, as soon as I walked in the door. Every member introduced themselves and made me feel welcome, which is true to crossfit community standards. I even got invited to their Christmas party. I had a great work out and had lots of fun. I highly recommend this gym to anyone. If you are ever in the St Louis area, Arnold CrossFit is the place to visit.
