The staff is very committed and the facilities are in good shape. Love the boxing class and the protein shake afterwards.

So far the three programs I've participated in here have been led by super qualified folks. Awesome experiences so far.

Best gym in the area! Many different group classes to keep you going led by trainers so you always feel motivated to work out! I've never felt that exercise "plateau" since I joined

Wonderful gym, workouts, and people! The only downside is that every other gym is boring by comparison so you can't ever move away.....
