The eponymous Barry Jay has made his mark on Southern California fitness through energizing, 60-minute group workouts that blend cardiovascular routines with strength training. The boot-camp program achieves the long-elusive dream of a funkier army by combining drill-sergeant-style motivation with dance-party fun. Dozens of classes (click on the "classes" tab) are held throughout the week, with each day's workout targeting different muscle groups to prevent the uneven development of a super-strong right calf. A team of instructors lead classes with energy and passion, helping students burn hundreds of calories per session.

The Irvine studio is the first Barry's to sport shower facilities, and its sleek open architecture frees arms and legs to fly through intense workouts while leaving nearby personal bubbles unpopped. The studio oozes with the program's universal energy and a fun military vibe that has attracted numerous Hollywood stars, such as Jake Gyllenhaal, Christina Applegate, and Kim Kardashian.
