Begin standing with weight on your left foot and right foot lifted a few inches off ground. Keeping your spine long, reach forward, bending your left knee and touching your fingers to the floor a few inches in front of left toes (as shown). Keep your abs engaged to stabilize your torso. Your right leg will go behind you to help you balance. Push through your left heel to stand. That’s 1 rep. Do 10 reps, then switch sides.
