Dumbbell Walking Lunge

Stand with your feet shoulder width apart and have a dumbbell in each hand.

Take a single step forward with one leg and begin to drop your hips until your rear knee is near to touching the floor. While performing this motion, your torso should remain upright.

Bring your self back up by driving through the heel of your leading foot and extend both knees.

Now step forward with the rear foot and repeat the lunge.
