Jump your way into fitness with the new Body-Solid Tools Speed Rope. Lightweight design with an extra-long non-kink rope. The easy grip handles are sure to make your jumping experience as comfortable as possible. While the main muscles that you're working are your calves. Jumping rope activates more muscle than you may think. - you're also using your shoulders (particularly your rear delts) as well as your abs, quads, hamstrings. Pretty much every muscle is firing when doing this exercise to keep your body stable. Jumping rope is a great calorie-burner. Jumping rope at a moderate pace will burn approximately 16 calories per minute for a 200-pound man. You'd have to run an eight-minute mile to work off more calories than you'd burn jumping rope for 3, three minute rounds.
