Hands down the best gym in Costa Mesa / Newport! Been going for almost 10yrs - best trainers, cleanest, friendliest, most motivating gym out there. THANKS for adapting during the past few months and am psyched you’re back indoors! 😁

The best workout I’ve ever had! I swear by the The 12 and have gotten friends to start doing their workouts! I just wish there were some gyms closer to Long Beach.

I haven't done any type of work out except yoga in years. After one session I was in love and freaking rocked with endorphins. This place is magical, all the trainers are great, all the people you work out with are great, it's just great end of story

My HIIT training gym shut down with no warning and I needed to find a replacement. I Decided to try out a class here and it is exactly what I was looking for; group fitness environment that is motivating and fun and challenging! So grateful to find there are two locations in Costa Mesa; as I was dreading having to join a traditional gym and take mediocre classes. 👏🏼💪🏻👍🏻
