Beach Fitness is a gym that offers a variety of classes in studio and even on the beach. It is the only gym in Old Town Seal Beach. It has a fun and innovative way of helping you achieve your fitness and wellness goals, including CrossFit since 2010, a staple program for group fitness. Although Beach Fitness has a Main Street address, the gym is actually along Central Avenue. Facing the beach on Main Street, turn left on Central Avenue and the main entrance will be the second door. It is next to Caribbean Tans.
