• Jumping Jack Challenge


      by Jill Yaworski Men's Health

      Jumping jacks are a great calisthenic, but they hardly scream, “This is going to be a brutal workout!” That’s about to change. For this weekend’s Train for Life challenge, kick up the intensity of this old-school exercise by performing a terrible trifecta of pushup jacks, squat jacks, and seal jacks. “These variations of the classic jumping jack will get your muscles burning and your heart pumping in no time,” says BJ Gaddour, C.S.C.S., metabolic training expert and owner of StreamFit.com.


      DO THIS

      Perform 11 pushup jacks, 22 squat jacks, and 33 seal jacks in a row. Then repeat. Test yourself by doing two rounds as fast as you can. Rest whenever you want, but keep the clock running the whole time. If that’s too difficult, try the modified challenge by removing the pushup from the pushup jack.

      Pushup Jack

      Assume a pushup position, your hands slightly beyond shoulder width. Your body should form a straight line from your head to your ankles. Jump your hands and feet out a few inches wider, while bending your elbows and lowering your body until your chest nearly touches the floor. Then push up with enough force for your hands and feet to come off the floor. Land in the starting position. That is 1 rep. Do 11.

      Squat Jack

      Stand with your feet together and your hands at your sides. This is your starting position. Jump your feet out to shoulder-width apart and lower down into a squat, reaching your arms straight out in front of your body at shoulder level. Immediately jump back up to the starting position. That’s 1 rep. Do 22 total.

      Seal Jack

      Stand with your feet together. Your arms should be straight out in front of your body at shoulder level and your palms together. Simultaneously squeeze your shoulder blades together, pull your arms out to your sides (they should still be parallel to the floor), and jump up just enough to kick your feet out wide. Without pausing, quickly reverse the movement and repeat. That’s 1 rep. Do 33 reps.
