About this studio

At MX3 Fitness, their trainers work as a team, utilizing their unique specialties and experiences to create a customized program just for you and what you hope to achieve. There are no “one-size fits all” or “cookie cutter” approaches with MX3 Fitness. And since the trainers work as a team, if your lead trainer is out of town for his sister’s wedding, another trainer can seamlessly pick up for him or her so you never miss a beat. 415 577 4307

Hip Hop Flair
Great class focusing on learning a specific routine for a song, unlike, say, a Rhythm/Fusion class at Alonzo King that combines a number of songs.
Total Body Training
Hard workout! Nice space in a small group setting.
Hip Hop Flair
So fun!
Hip Hop Flare
Fun class and judgement free of all skill levels
Total Body Training
The studio is clean and the routine was challenging, but the trainers playlist was not great which is a make or break for me! I also would prefer classes to be longer and include more stretching time.
