Client Testimonials

We went to a birthday party here and then decided to sign my seven year old up for classes and he loves it. We've been going here almost a year now and we couldn't be happier.

Joy Chambers

The coaches are so helpful and encouraging. The motivation and push I need during the exercising is outstanding.

We came for an open gym slot and it was super easy to make reservations online and sign the waiver!

There were many obstacle courses that you can do and it is divided into the "kids" section and "adult" section, but it is by no means "easy." Things are just shorter and closer in the kids section so it's a good place to warm up and take it easy while learning the foundations/ basics so you won't hurt yourself.

2 hours passed by very quick lol. We spent most of our time practicing on the warped walls, pushing to ones that are taller as we get comfortable with it.

Rebecca Jung

Since I've been wanting to get a little better at obstacle courses, I decided to check out a gym designed just for that. Apparently, some of the customers/staff here have been shown on America's Ninja Warrior! Definitely adds to their credibility. Also, from their ONE session solely on how to control your balance, helped with an obstacle I had today at a race. I was able to walk across a beam without falling into the water. Honestly, their training works and I hope to learn more before my next race in August.
