Can't say enough good things about this place. Never did I think I'd be wearing size 31 pants again, and yet I am. Never did I think I could enjoy a leg day, and now it's my favorite day of the week. The front desk team, the trainers, the facilities, the workouts, the other members - all undeniably top notch. The12 has become a constant in my life, and whenever I'm traveling and can't make it, I feel the effects. The12 is more than a place you go workout, it's a community, and it's a lifestyle. I'm beyond grateful for having... read more

The 12-Costa Mesa is the best gym in Orange County! The energy level is insane as soon as you walk through the doors. The staff and all of the trainers are friendly and welcoming. I've been coming here for about two months now and I don't think I can ever go back to another gym. Love this place and love Sarah! If you want a good workout and want to challenge yourself take her classes!

I've been coming to The 12 for almost 6 months & now I can't imagine my life without it. I'm now someone who loves coming to the gym thanks to this amazing place!!! The 12 has unreal trainers who push you to be better every time you come to class. What sets The 12 apart is the incredible environment full of energy and the welcoming, diverse, fun members!!

Absolutely in love with The 12 and its incredible community. I was super intimidated before my first class, based solely on what I *thought* it would be like. A few seconds after walking in the door, I realized anything I had thought was wrong. I mainly take Sarah's classes at the CM location and am OBSESSED - the environment is so supportive, friendly, and welcoming that it's hard not to be. Every single person I have met at The 12, without exception, has made me feel like I belong. The workouts are also unreal, in the best... read more
