Highly recommend for an excellent tread & strength class. Great coaches who know how to motivate and challenge, fun and eclectic music, and a great community atmosphere. No two classes are ever the same. Positive vibes and encouragement make every workout enjoyable and you leave knowing you accomplished something significant.

I’m one of those hard to stay motivated exercisers. Momentum is just what I needed. The coaches are great, the other clients are friendly, and the work outs make me feel proud. As soon as I walk in and hear the music I’m ready to lock in and enjoy the workout.

I was visiting my sister who recently moved to Oak Park and I needed a workout class. I walked by this gym and went in to acquire about possible classes and right off the bat I was greeted and invited inside to see the gym, even though the gym was closed. The staff was so friendly and inviting and encouraged me to sign up for a free class to try it out. I eventually tried the free class and I wish I had signed up sooner because I left feeling so great and had the best workout. I wish I lived close by because I would’ve signed up for a membership the next day. I encouraged my sister and brother in law to try out the class!!!
