Stand with both feet together. Shift weight onto your left foot, lift your right leg off the floor, and bend the knee behind you. Hold either the ankle, inner arch, or the big toe with your right hand. Lean forward, lifting your right leg as high as you can, extending your left arm in front of you to help you balance.
Stay like this for five breaths, release hold of your foot, and repeat this pose while balancing on the right leg.
