Jumping rope might seem like kid’s play, but when it comes to burning calories, wise adults grab a rope and hit the pavement. If you want to boost your weight loss efforts, a jump rope is a valuable exercise tool. Performed regularly, jumping can also improve heart health and build endurance. The number of calories you burn and pounds you lose depend on your weight and the amount of energy you put into the exercise. The longer and faster you jump, the more you stand to lose.
