Stand holding dumbbells at your sides and palms facing in. Another variation is to use one heavier dumbbell which would be held on the side of your supporting leg, with your other hand on your hip as you perform the movement. Bend forward at the hips as you raise one leg behind you, squeezing your glute as you do so. As you do this, bring the dumbbell(s) down so that they almost touch the floor, and pronate or twist your wrists so that your palms face your body as the weights come towards the floor. Return to start. Make sure to keep your knees soft throughout this movement, and if you have issues with your knees, maintain a slight bend in them. You will perform all repetitions on one leg before switching to the other side.
