Kicks: Start with your feet together. Step back with your right foot. Kick your left foot back behind you.
Step back to starting position with your left foot, then kick your right foot forward.
Step back to starting position with your right foot, and repeat these steps.
Swings: Think of the arm movement as if you're walking -- when your right foot goes back, your left arm swings forward, and vice versa.
Put the arm and leg movements together. The dance should be exaggerated, like you're flailing around.
