The Power of Groups: Group Exercise at the J
18 years+ Unlimited, free group exercise is an amazing benefit of membership at the J – and group ex itself offers many benefits, too! The energy is positive and high in a group class, you make new friends, look forward to seeing each other and become accountable to each other, and you tend to work a little harder in a group. Between our two locations and our virtual library, the J offers nearly 150 free classes each week – and this includes the most popular classes like yoga, cycling, Zumba and Tabata.

To improve the experience for members, we will now have a time limit for class reservation cancellations. Members can cancel their reservations up to one hour prior to the start of class, but no later.
Members attempting to cancel their reservations later than one hour will be unable to do so and will be considered “no-show” if they do not attend.
Thank you for understanding as we ensure our classes are available for as many members as possible.
Fitness Studio Use Rules
Studios are only for use when an instructor or trainer is present. This includes entering a studio early to set up equipment or staying after a session to stretch. In all situations, a trainer or instructor must be present. For safety and security reasons, working out alone in a studio is not permitted under any circumstances. Studios will be locked between sessions when they are not in use.
RSVP & Waitlist Policy
Reservations are required for every class and become available 48 hours prior to the class time.
RSVP’d members will have a five-minute grace period from the time Group Exercise class begins. If you are more than five minutes late for class, and there is a waitlist, a waitlisted member will be allowed to join the class in your place.
