Version one: Lying on your back with your knees pulled in tight to your chest, slowly lower your knees to the ground (or as close as you can) on one side of your body. If your knees do not reach the ground you can prop them up with a pillow or yoga block. Then proceed to circle the back arm (if you dropped your legs to the right this would be your LEFT arm). Do five circles in one direction, then change direction for five more circles.
Version Two: Start lying on your side. Bend your top leg/knee into your chest and rest it on a yoga block (or two) in this bent position. Keeping your hips and shoulders stacked, turn the thumb of the top arm to the ceiling. Inhale, and as you exhale lift the arm to the ceiling and and reach for the ground behind you. Repeat this action 5 times, holding the fully twisted position on the final repetition for 30 seconds.
