2 BACK MUSCLE BOOST

PREVENTS neck, shoulder and back injuries, and helps maintain good posture.

TAKE a pair of tights and hook around a doorknob in front of you at hip height.

STAND a few feet away and pull it towards you with both hands as far as the hips.

KEEP elbows close to your body so you can feel shoulder blades squeeze together. Do ten times, rest for a few seconds then go twice more.
