From Our Students

I Flex because it provides workouts that I love enough to actually do! And if I stop showing up, members and instructors will notice, and they care enough to reach out and see if I'm doing okay. Gone are the days of paying for a gym membership I never use. Gone are the days of anonymity and feeling like I'm going it alone in my fitness journey. I'm never leaving Flex!

Linda S.

Flex is not your typical Silicon Valley cookie cutter studio. There is a true sense of community, talented instructors that are invested in you, and a never-boring mix of classes! Plus, it’s locally owned.

Ashley N.

I have taken over 500 barre classes all over the country and Barre Burn at Flex is in my top five favorite classes of all time!

Kayla B.

In a sea full of corporate studios, Flex stands out because of the authentic, personal workouts and community. It’s wonderful to have genuine instructors and staff who know you by name

Christina C.

The individual attention and care! It really emphasizes that I don't have to be in competition with anyone, I'm not just another face in the mirror or body on a mat. My fitness journey and goals are just as valid as anyone else's and it's ok to modify or go at my own pace.
