The energy in the studio is truly unmatched. It’s upbeat, positive, and empowering the moment you walk through the doors. The entire staff—from front desk to instructors—is kind, welcoming, and always willing to help with anything you need. But what really sets this place apart is the community. Everyone is encouraging, supportive, and genuinely happy to be there. Whether it’s your first class or your hundredth, you feel like you belong.
I am a dad of 3 young boys and this place has been a God send. I am able to get in, get an intense workout in, and be home without any lazy downtime. Moxie has changed the way I look at fitness and has allowed me a renewed joy in fitness. I would recommend to anyone who is looking for a diverse class based fitness center! There truly is something for everyone.

On Sundays at 4:00pm, classes for the upcoming Tuesday-Monday will go live for booking. Memberships grant you early access, with booking opening on Fridays at 3:00pm.
Classes cancelled before 5:00pm the night before your class will be credited back to your account with no penalty.
Our classes often have waitlists and late cancellations/no-shows can reduce waitlisted guests’ ability to attend class. As a result we have implemented late cancellation and no show fees to hopefully deter these types of cancellations from occurring. Classes cancelled after 5:00pm the night before your class will result in a $10 charge and loss of credit. No-shows will results in a loss of credit and a $20 no-show fee.
We will hold your spot until two minutes before class start time. At the two minute mark, we may release your spot to a guest on the waitlist. We recommend calling the front desk if you anticipate arriving late.
