Start by lying flat on the mat with the palms facedown on the floor. While inhaling, roll the chin to the chest and lift the left leg. Then, bend your right knee into your chest, forehead to the knee and shoulders rolled slightly off the ground. Take the hands to the right shin and then tug the knee slightly closer to the chest with each little exhale. Inhale as you switch legs and arms to the other side and repeat. Point the toes and use your abdominals to keep your lower trunk stable and glued to the mat. Do five repetitions on each leg.
