All of the teachers are wonderful and experts in the field.

Lovely, helpful staff; judgment free zone!

It's a great, community-centric, body-positive place.

If there were 10 stars, mActivity would get them!

The teachers are great at teaching a variety of classes that include cardio, barre, stretching and yoga.

Beautiful setting, variety of equipment, expertise of professional staff of trainers. Everyone has a place here, athletes, seniors, etc.

Great selection of group classes (barre, HIIT, etc), good vibe at the gym overall!

mActivity creates such a positive environment that I absolutely look forward to working out, and I go multiple times a week now.

There are so many things I love about mActivity; first and foremost, it's the first gym I've ever attended consistently!

There is a happy feeling that I get when coming into mActivity... I couldn't ask for more in a gym or community of this sort!!
