Lie prone on the floor. Stretch your legs back, with the tops of your feet on the floor. Bend your elbows and spread your palms on the floor beside your waist so that your forearms are perpendicular to the floor. Inhale and press your inner hands firmly into the floor and slightly back. Then straighten your arms and simultaneously lift your torso up and your legs a few inches off the floor. Keep the thighs firm and slightly turned inward, the arms firm and turned out so the elbow creases face forward. Press tailbone to pubis and pubis lifted towards navel.
