Dumbbell Reverse Lunge
STEP 1. Hold a pair of dumbbells at arm’s length at your sides as you stand with your feet shoulder-width apart, toes pointing forward.
STEP 2. Step back as far as possible with your dominant leg and drop down until that knee grazes the floor, keeping your torso as upright as possible.
STEP 3. Push through your forward heel to return to the starting position, then immediately lunge back with that leg. That’s one repetition.
