To prevent or alleviate tight shoulders, try these three key stretches, courtesy of the American Academy of Orthopaedic Surgeons.
Stand in a doorway, facing the frame, and bend left arm 90 degrees to touch the frame. Rotate torso to right without moving legs. Hold for 30 seconds. Repeat on other side.
Crossover arm stretch
Gently pull right arm across chest, just below chin, as far as possible without causing pain. Hold for 30 seconds. Repeat on other side.
Lie on back with legs straight. Use left arm to lift right arm overhead until you feel a gentle stretch. Hold for 15 seconds and slowly lower to start position. Relax and repeat on other side.
