Hold your right wrist over your head with your left hand and pull it, stretching your right side. Heidi says make sure to keep your shoulders down as you bend. Hold for 10 seconds. Return to upright posture. Take hold of your left wrist over your head with your right hand and stretch the other way. Repeat five times on each side."
