HOW: Begin in a standing position with your feet about shoulder width apart. Hinge forward at the hips, and bend your knees into a deep squat all the way down to grab onto your toes. Once your hips are as low as you can go, rotate your chest to one side bringing that arm straight up and the other arm straight down, then do the same on the other side. Finally, raise both arms up overhead and return to the standing position.
FEEL: You should feel your leg muscles working. You should also feel a stretch in your shoulder and mid back.
COMPENSATION: Keep your feet flat on the ground. Make sure you are as deep as you can squat before you rotate your chest.
