HOW: Stand facing a wall and place both hands on the wall at shoulder height. Lean into the wall by gentle letting your stomach muscles relax. Try to bring your belly button to the wall in front of you slowly. Keep your elbows straight as you sink your hips forward into the wall back and forth slowly.
FEEL: You should feel a stretch in your low back.
COMPENSATION: Stay relaxed! Only allow the hips to go forward, your back will follow your hips!
