Barbell Straight Leg Deadlift form demonstration - targeted for Hamstrings Upper Legs workouts

Barbell Straight Leg Deadlift

The straight leg deadlift trades the bent-knee version's quad involvement for a much sharper hamstring and glute stretch at the bottom of each rep. Keeping the knees nearly locked shifts the hinge almost entirely to the hips, which is why it's often used to build hamstring flexibility as much as strength. Go too heavy too soon here and lower back rounding creeps in before the hamstrings actually give out.
