Gold's Gym is famous for turning out muscleheads—the original Venice Beach location, opened by Joe Gold in 1976, was called "The Mecca of Bodybuilding." Today, with more than 600 U.S. locations, Gold's is a gym for everybody, offering a wide variety of classes, weightlifting and calorie-burning machines, personal trainers (male and female), a pool and some very non-gross locker rooms. Of course, there are still plenty of hard-core bodybuilder dudes there.
