How to Do Jumping Jacks Calisthenics Exercise

Most calisthenic exercises are staples of school gym classes and boot camps, but that doesn't mean they're outdated. Most, like jumping jacks, are still excellent ways to get into shape. Jumping jacks work your shoulders, back, thighs and calves. They're also good for your heart. The following steps will take you through this exercise.

Instructions

Difficulty: Moderate

1. Begin by standing with your feet together and arms at your sides. Tighten your abdominal muscles to pull your pelvis forward and take the curve out of your lower back.
2. Bend your knees and jump, moving your feet apart until they are wider than your shoulders. At the same time, raise your arms over your head. You should be on the balls of your feet.
3. Keep your knees bent while you jump again, bringing your feet together and your arms back to your sides. At the end of the movement, your weight should be on your heels.
4. Repeat the exercise, working in sets and resting briefly in between. As you become more fit, perform jumping jacks faster and for a certain length of time rather than in sets.

Tips & Warnings

• Jumping jacks are called star jumps in some countries, because your arms, legs and head form a five-pointed star.
• Don't clap your hands together as you raise your arms overhead, and if you have stiff shoulders, you might injure yourself by trying. Raise your arms only as far as you comfortably can.
