Start by standing with your feet shoulder-width apart and holding a dumbbell in each hand. Your palms should be facing your body.
Hinge at your hips and bend forward, keeping your back straight. You should feel a stretch in your hamstrings.
Raise the dumbbells up to your sides, keeping your elbows close to your body. Squeeze your shoulder blades together at the top of the movement.
Lower the dumbbells back to the starting position.
