Body-Solid Jump Rope Jump into fitness with the Body Solid Tools Speed Rope, designed for efficiency and comfort. Its lightweight construction features an extra-long, kink-free rope, and the ergonomic, easy-grip handles ensure a smooth and comfortable jumping experience. While your calves are the primary muscles worked during rope jumping, this exercise activates more muscles than you might think. It engages your shoulders (especially rear delts), abs, quads, and hamstrings—pretty much every muscle is involved in keeping your body stable throughout the movement. Jumping rope is an excellent calorie-burner. A 200-pound person will burn approximately 16 calories per minute at a moderate pace. In fact, jumping rope for three 3-minute rounds burns more calories than running an eight-minute mile.
