Target muscles: side of trunk and shoulders, also the outer thighs and hips when performed in a standing position
Sit tall against the back of a chair or stand tall with feet shoulder-width apart or wider. Gently bend the trunk to one side as the opposite arm reaches up above and then across the head to form an arc. Keep the head, chest, and hips facing forward throughout the stretch and breathe evenly. Hold the position for 5 to 15 seconds, and then slowly return to the starting position. Repeat on the opposite side.
Alternating Hip Lifts
Target muscles:oblique muscles of trunk, hip flexors, knee flexors
Place both hands on either side of a chair. Slowly raise one hip off the chair. Hold raised position for 10 to 20 seconds before lowering hip back down. Repeat on the opposite side.
