1 - Stand with your feet hip-width apart, with the barbell resting on the floor or in a rack at hip height in front of you.
2 - Grip the barbell with an overhand grip, hands just outside shoulder-width apart.
3 - Keep your chest up, shoulders back, and maintain a slight bend in your knees throughout the movement.
4 - Hinge at the hips, pushing them back as you lower the barbell down along your legs, feeling a deep stretch in your hamstrings.
5 - Lower the bar until you feel a strong stretch in your hamstrings or until the bar reaches mid-shin level, keeping your back flat and neutral throughout.
6 - Drive your hips forward and squeeze your glutes to return to the starting upright position in a controlled manner.
7 - Repeat for the desired number of repetitions, maintaining tension in your hamstrings and a neutral spine throughout.
