Underground Fitness CA

The trainers at Underground Fitness II inspire their guests to conquer their fitness goals—big or small—through high-energy group workouts in an encouraging atmosphere backed by heart-pumping beats. They also integrate plyometrics, which typically focus on non-weight workouts such as box jumps and squat jumps. During Zumba and U-Jam classes, the instructors transform the studio into a club scene, as patrons bust a move powered by pulsing Latin or hip-hop tunes.

To help patrons recover from vigorous workouts, a team licensed physical therapists stand at the ready to massage muscles, making more relaxed than a sloth tubing down a tryptophan river.
