THE FLAGSHIP

The Costa Mesa studio, our first and largest location, offers three core class formats (Strength, Shred and Cycle), as well as a variety of recovery services and personal training.

What started as a tent in a parking lot in 2020 is now a neighborhood landmark and the site of most of our special events and community gatherings.

FROM OUR MEMBERS

★★★★★

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.
