Jump rope--keep your head up, eyes forward, elbows close to the body, and let your wrists drive the rope around. Jump just high enough to allow the rope to pass under your feet. Land softly on the balls of your feet. Then swing the rope a little faster so it passes under your feet two times per jump. Aim to do 20 jumps without getting tangled.
Build on It: Work up to two minutes.
