The good morning works the hamstrings, glutes, and lower back with a barbell across the shoulders.
Standing with the barbell resting across the upper back, feet hip-width apart, knees slightly bent.
Hinge the torso forward by pushing the hips back with a flat back until you feel a stretch behind the thighs, then return to the starting position.
Start light: the back must remain flat throughout the entire range of motion.
