How-to: Reverse Lunge with Touch-Down
Place the ball dome side up. Stand on top of it with feet hip-distance apart and reach your arms up by your ears, palms in and shoulders relaxed (A). Step your left foot back onto the floor behind you, bending your right knee to 90 degrees to come into a low lunge. At the same time, hinge forward at the hips and touch the dome of ball on either side of your right foot (B). Next, push off with your left foot and return to standing on the ball, arms reaching up. Do 12–15 reps, then switch sides and repeat.
No gym or BOSU? Do the same exercise with both feet on the floor. To add more of a balance challenge, lift your knee after each lunge instead of returning to the starting position.
