This is a great gym overall but I especially liked that the coaches got me motivated again to work out after I had been losing interest in going to the gym for over 6 months. The energy, fun, and encouragement of the coaches and other gym members is why I keep going.

I joined US in September 2023 with limited balance and mobility issues. I started to work with Coach Brenner on my journey to become stronger. I cannot say enough great things about Brenner. He is a great trainer that motivates, inspires, encourages and pushes you to work through your weaknesses. He understands your goals and helps you reach them without judgement. It has been a privilege going to US and working with him. It has been transformative for me. I highly recommend Underlying Strength!
