Lake Los Angeles Gyms and Fitness

At the end of a fruitful career that led her from the Cincinnati Ballet to the Sacramento Ballet, Jennifer Williams funneled her dance savvy into creating the barre-inspired exercise system taught at Pop Physique, a 2009 CityVoter nominee for Best Gym. Her fleet of handpicked and personally trained instructors pairs graceful ballet moves with other low-impact exercises in order to chisel cores without injuring muscles. Deep stretches further preserve tendons and leave each student more relaxed than a tortoise moseying past a state patrolman with a radar gun. Sessions run multiple times a day, seven days a week at an expanding network of SoCal locations. The roomy studios are lined with sprung dance floors and design accents that lend each location a distinct personality and a chance to forget its past as a storage room for defective food processors.

Teachers also divide their attention among students of all levels during group classes, which range from Level 1 mat sessions to dynamic Nia workouts. Nia blends elements of dance, martial arts, and the healing arts into a series of 52 movements that rotate from session to session to keep muscles from getting bored.

Fitness blooms at three locations, which together host more than 130 classes each week. The Studio City location surrounds exercisers in rustic wooden walls, in contrast with the floor-to-ceiling mirrors and undulating modern lines of the Porter Ranch studio's décor. Mat classes at The Annex stretch and bend beneath a large photo mural of a forest so that students can draw inspiration from branches' ability to hold themselves indefinitely in plank pose.
