A Type of Jumping Jacks for Interval Training

You will move your legs as you do in a jumping jack (legs in and out). Your arms, however, will move differently: Keeping your arms straight, bring your arms from out to your sides to almost touching in a clap in front of you. When your arms move closer your legs more apart. Do this "jump" for a minute. Rest for 30 seconds. Repeat the "jump" for a minute. Rest for 20 seconds. Repeat the "jump" for a minute. Rest for 10 seconds. Repeat the "jump" for a minute. Rest for 5 seconds. Repeat the "jump" for a minute. Breathe deeply.
