Stand with feet hip-width apart on a bench or raised surface holding a barbell. Keep knees slightly bent and back neutral. Hinge at the hips and lower the barbell toward the floor by pushing hips back while keeping the bar close to your legs. Feel the stretch in your hamstrings, then drive hips forward to return to standing. Repeat for reps.
