Lie face down on a decline bench with your knees just off the end and hold a dumbbell securely between your feet. Bend your knees to curl the dumbbell up toward your glutes, keeping your hips down and core engaged. Slowly lower the dumbbell back to the starting position with control, focusing on engaging the hamstrings throughout the movement.
