Stand with your feet hip width apart and hold a pair of dumbbells just outside of your legs. Keep your feet pointing straight ahead with your weight on your heels and a slight bend in your knees.
Keep your chest up, shoulders back, and chin tucked with your neck in a neutral alignment.
To start the movement, focus on pushing your hips back while maintaining a slight arch in your lower back. Extend your hips forward until you feel a good stretch in your hamstrings. Once you feel that stretch, pull the weight back up by pushing your hips forward.
Squeeze your glutes and hamstrings at the top of the movement, and then repeat.
