You probably haven’t jumped rope since grade school, but don’t worry, with a little practice it’ll all come back to you. Jumping rope is not only a great cardiovascular workout but it works neurological skills like agility and coordination. Jumping rope will have all the muscles in your legs working, the core is engaged during the jump, as well as the shoulders, arms, and wrists during the rotation of the rope. Just make sure your rope is the right size. Folded in half, it should reach from the ground to your shoulders.
