I have been going to CrossFit Jungle Gym for almost 3 years now. The owner keeps the place spotless and upgrades equipment on a regular basis!!

I came across Crossfit Jungle Gym pretty haphazardly after being curious about crossfit in general and I've been blown away by my experience so far. Brian, the owner, conducted a thorough onboarding process focusing on my goals, expectations, and hesitations. Every coach has been incredible (Jim, James, Nancy, Eric, Jen...sorry if I'm leaving anyone out!). Class sizes are intimate and the coaches are intuitive and know when to push you or back you off. Being new to this kind of training in general, everything felt a little overwhelming at first but the coaches and members have been welcoming and this has quickly become a new staple in my life. I'd recommend it to anyone with a real desire to improve their well-being.

I dropped in for a week. The program is structured well and the couch was awesome. I would go back again the next time I'm in town.
