If one side of your back feels a little tighter than the other, perform this stretch on a regular basis. It's a simple, excellent way to bring flexibility and balance to both sides of your torso.
Start by kneeling on a padded surface or mat. Position a yoga block on the floor just to the right of your body. Place your right foot on the floor with your toes, knee and thigh pointing to the right. Be sure your right heel is lined up across from your left knee. Lift your chest and let your arms hang straight down. Keep your hips forward, below your chest.
