Set the Smith machine bar at shoulder height. Position the bar across your upper back, hands slightly wider than shoulder-width. Unrack and step forward with one foot. Lunge, keeping your front knee aligned with your ankle. Lower your back knee towards the ground, maintaining an upright torso. Push through your front heel to return to the starting position. Repeat, alternating legs.
Avoid letting your front knee extend past your toes. Maintain a straight back and engaged core. Control the movement throughout. Adjust foot placement for optimal range of motion. Start with lighter weights to ensure proper form.
