Stand with your feet slightly wider than your hips. Bend your knees, and lower your hips down toward the ground. If your heels don't touch the ground, roll up a towel or the back of your mat, and place it under your heels for support.
Bring your palms together at your heart centre, and firmly press your elbows against the inside of your knees. This will help to open your hips even further.
After five breaths, release your hands to the floor and walk them away from your feet to increase the stretch in your hips and lower back. Hold for another five breaths.
