At Curves, exercisers of all fitness levels move around a circuit of hydraulic-resistance machines that have been designed to work with women's bodies and promote weight loss, protect against osteoporosis, and deal with arthritis. An experienced trainer is always nearby to help manage machine-maneuvering and muscle making. Instead of fiddling with weight stacks, filling medicine balls with medicine, and losing your momentum, the hydraulic machines account for different body weights and fitness levels to create resistance that matches one's abilities, which thereby decreases the risk of soreness or injury. Because traditional lift-and-lower motions create bulky muscles, each machine uses push-and-pull motions to create toned, lean muscles perfect for crushing a grapefruit without looking like you can.
