Do the Twist by placing your feet hip width apart and transferring your weight to the balls of your feet. Twist your hips from side-to-side, letting your entire lower body swivel to the beat of the music.
Do the Pony by hopping to the side on your right foot. Bring your left foot into your right and take a small step onto the ball of your left foot before quickly stepping on your right again. Repeat with your other leg.
Continue doing the Twist or the Pony and begin moving your arms in one of the swimming motions.
Make "freestyle" strokes as your continue moving your lower body. Bring your right arm behind your body and circle it toward your head with the elbow bend. Extend your hand straight forward in line with your ear and repeat the motion with your other arm.
Act like you are jumping into the pool or ocean. Hold your nose with one hand and wave your free arm back and forth. Bend your knees and lower your body so it looks like you're ducking under the waves. This style of arm movement works best with the lower body twist.
Add backstrokes to your lower body movement. Keep your arms straight and your fingers together. Circle your arm in front of your body and back toward your head. Tilt your torso back slightly so it looks like your strokes are propelling you backward.
Alternate between different kind of "strokes" as you dance. Try mixing and matching the different lower body movements with the swimming motions of your arms.
