Exercise IV: Dumbbell Single-Leg Lunge on Bench
Reps: 10 (Each Leg)
Stand a few feet in front of a bench, bend your right knee, and rest the top of your right foot on the bench . Keeping your torso upright, bend your left knee and lower your body until your right 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 10 reps and then switch legs.
