Not Jewish? No worries! The JCC's great facilities are open to everyone, which is great news seeing how it's one of San Francisco's finest health, fitness, and aquatics centers. Offering more than 160 group exercise, mind-body, and aquatics classes — including yoga, tai chi, boxing, Qi Gong, and Pilates — per week, you'll rarely have to do the same workout twice. Oh, and did I mention that there's a spa too?
