Jump Cross, Jump Heels
A fast exercise on weight shifts, jump crosses and heel jumps, with the arms working too. Both the feet and arms move fast, so every position is fully extended. Jump together, then shift your weight to one side with the knees still pointing front. The body stays low in plié, tilted slightly forward.
Arms cross in front, then open with the elbow popping out. The jump heels take the weight from one foot to the other, with a flexed heel and a push of the opposite hand. Slow counts first, then fast.
