Begin standing with all your weight on your left foot.
Keeping your spine long, reach forward, bending your left knee and touching your fingers to the floor a few inches in front of your toes. Keep your abs engaged to stabilize your torso. Your right leg will go behind you to help you balance.
Press your left heel into the ground as you lift your torso to stand, bringing the right foot to touch next to the left foot. This completes one rep.
