Stand upright holding a dumbbell in each hand in front of your thighs. Shift your weight onto one leg while keeping a slight bend in the knee. Hinge at the hips and lower your torso forward while extending the free leg straight back behind you for balance. Keep your back flat, chest facing the floor, and dumbbells close to your supporting leg. Lower until your torso is nearly parallel to the ground or until you feel a strong stretch in your hamstrings. Drive through the heel of the working leg, squeeze your glutes, and return to the starting position under control. Switch legs after completing the set.
