Stand straight with your feet shoulder-width apart, holding a barbell before your body.

Maintain a slight bend in your knees and hinge at your hips, pushing your butt as far back as possible. Lower the dumbbells along the front of your legs as you hinge forward.

Pause momentarily at the bottom of the movement, then reverse the motion by squeezing your glutes and hamstrings to raise your torso to the starting position.
