We offer group fitness classes 7 days a week. We have both morning and evening and night classes that are sure to fit your schedule. Our classes are perfect for both men and women and suit all fitness levels (beginner through advanced). 


We do recommend that you sign up for classes online ahead of time if you want to be guaranteed a spot. Once you purchase a class package from your gym, visit our weekly class schedule to pre-register for the class of your choice. You can register up to a week in advance. 

Please Note: We require 24 hours notice to cancel your registration without being charged for the class.


Drop in class rate $10.00


Why Clients Love Us

Haven't found a program I like this much in years

Andrew Haynes is the originator of Cardio CUTZ, my favorite class! I'm a devoted attendee of Liz's class on Mondays at the Charles River YMCA. It is such a wonderful class; I feel great and motivated to come back every week. I actually haven't found a program I like this much in years. - Nicole T.
