What our Members are Saying About Bella Strength!

“The best gym I’ve ever experienced. Great coaching, good camaraderie, fun and supportive atmosphere.”

Laura Yasuda

“If you truly care about getting in shape and want to be pushed both mentally and physically this is the gym for you. The strength and conditioning combinations increase strength while also increasing your cardiovascular threshold. No one does it better!”

Adam Wertz, Your Content Goes Here

“Possibly the cleanest gym in Boulder, with lots of top end equipment. Great coaching and I love the organization into mesocycles so we can see real improvement across our lifts/movements!”

Andy Newman

“Bella Strength is by far the best gym I’ve ever been to. It offers a personalized experience where the coaches know you and your individual goals and injuries or mobility limitations, with the fun of a group ex environment. Everyone is laid back and friendly, but also serious about proper technique. I’m constantly being challenged and learning something new. After 6 months at Bella, I am stronger than I have ever been.”
