Start standing with both feet flat on the ground. Bring your left forearm to the chair/support and place your right arm extended straight out to the side at shoulder level with your thumb facing up. If you need a modification, you can place your right hand on your right hip.
Lift your right leg about a foot off the ground, and pulse your leg up a few inches.
With control, lower your right leg back down a few inches. Your right foot should never touch the ground.
