Start standing and begin to prance starting with your right leg (it should look like you're peddling your feet in place).
Prance right and then prance left with your arms in first position; prance right, prance left with the arms above the head; prance right, prance left with the arms out to the side; prance right, prance left with the arms held in a low fifth position.
Repeat the same the combination adding small jumps (this should look like low variation of high-knees).
