Class Schedule

Class Reservations Matter!

Please reserve your class ahead of time. It helps our coaches prepare for class, plan equipment, anticipate class size, and be ready to provide the best coaching experience for everyone.

You’ll also notice there’s a cutoff time for reserving or removing yourself from class. This gives coaches time to review the roster and prepare before class begins.

If something comes up after the cutoff, no problem—life happens! Just send a quick message to the coach scheduled for that class so they’re aware.

Thanks for helping us make every class run as smoothly as possible!
Welcome: Yasmin & JASON V
