Did some drop ins when we were here in Maui. Tom and Janelle are amazing and the gym is outstanding. The program is great and the gym is clean. They make you feel like a part of their Ohana. We try to drop in every time we come with my parents and it makes our time on Maui extra special. See you next time 🤙

We did multiple drops ins while on vacation in Maui. This gym is a part of our hearts on Maui. It makes our trip feel extra special and feels like we are reuniting with family from the moment we walk in. The program is great for all of our family who crossfits at home. We have a blast here. Thank you.

This is not only the best gym in Maui, it’s the best gym on any of the islands. Tom and Janelle (and their community) make any guest feel welcome and like part of the crew. I’m always excited to drop in every time I come to Maui. Can’t recommend this gym enough!
