Start standing with your heels touching and your feet turned out in a "V" shape. Bring your elbows in by your rib cage with your arms open to 90 degrees and your palms facing forward.
Keeping your heels together, press through the balls of your feet, and lift your heels off the ground, bending your knees as you lift your heels. Simultaneously reach your arms straight out to the sides.
Lower your heels back down to the ground, straighten your legs slightly, and bring your arms back to your rib cage.
