    Jumping rope is an excellent exercise to help improve stamina and conditioning, but jumping rope can get pretty boring the better you get at it. One method to make jumping rope more challenging is to do “Double Unders,” which means you swing the jump rope two times underneath your feet with only one jump. For a beginner’s tutorial on how to jump rope, check out this article: .

    As you can see in the video above, a double under requires that you jump much higher than a normal jump rope revolution. In fact, you can jump just an inch off the ground during your normal jump rope routine, but a double under requires you to jump much higher. Jumping higher and slower helps create enough time for you to swing the jump rope 2 times underneath your feet as opposed to just once. As you get better and more efficient at doing double unders, you won’t have to jump as high.
