Stand with your feet about shoulder-width apart inside a Smith machine and grip the bar with an overhand hold. Keep your knees slightly bent and back straight as you hinge at the hips, lowering the bar toward the floor while feeling a stretch in your hamstrings. Reverse the motion by engaging your hamstrings and glutes to return to standing, controlling the movement throughout.
