Exercise III: Single-Leg Lunge On Bench
Reps: 12 (Each Leg)
Stand a few feet in front of a bench, bend your left knee, and rest the top of your left foot on the bench . Keeping your torso upright, bend your right knee and lower your body until your left knee touches the floor (but do not rest it on the floor) . Reverse the motion to return to the starting position. That's one rep. Perform 12 reps and then switch legs. When you can perform three sets of 12 reps, add dumbbells to the exercise.
