THUMBS UP

By building up your shoulder blade and upper back muscles, this exercise helps prevent neck pain and strengthens the posterior deltoid muscle (which is responsible for preventing hunched shoulders).

WHAT TO DO

✓ Lie prone, on your stomach, with your arms stretched out.

✓ Make a fist with each hand, and stick your thumb up to the ceiling.

✓ Pull your navel to your spine as if you were trying to lift your stomach off the ground.

✓ Squash your legs together as tightly as possible without lifting them off the ground.

✓ Keep your head on the ground with your chin tucked in.

✓ Raise your arms off the ground, but make sure that your feet and head stay on the ground while doing this.

✓ Hold for 15 seconds, and repeat five times.

LOOK OUT FOR

✓ Make sure your thumbs always point to the ceiling and your shoulders are pulled away from your ears.

✓ As with the previous exercise, try as hard as you can to keep your navel to your spine to protect your lower back.
