Do 6 open-book spine twists per side

Lying on your side, open your top arm across to the other side.

Why it helps

Upper back mobility often suffers from desk work. This move gently twists your ribcage where it is meant to rotate.

How to do it

1. Lie on your side with knees bent and arms straight in front.
2. Lift your top arm and open it back, following your hand with your eyes.
3. Return and repeat six times, then switch sides.

Make it easier

Rotate only as far as comfortable.

Make it harder

Pause for three breaths with your arm open.

Move slowly and stop if you feel pain.
