Child pose with a twist ("Child's pose" Shoulder/trunk extensors stretch, with side bending, kneeling)

Kneel on the floor and sit on your heels.
You can place cushions underneath your hips if you need to.
Stretch your arms out in front of you, and walk our hands over to one side.
Keeping your hips over your heels, turn your outer palm to face up, and place the other hand on top.
Arch your outer side up a little as you reach to the side to increase the stretch.
