Jumping Jacks were one of my favorite exercises as a child, and one of the ones that as an adult makes me the most self conscious to do.

For the jumping jack you assume a upright stand with your legs together and your arms straight down to your sides. In one smooth move jump up, separating the legs and lifting your arms so that when you land your legs are just slightly more than shoulder width apart and your hands are clapped together high above your head.

Return to the starting position using another jump motion to lift you into the air as you draw your legs back together and lower your arms back to your sides.
