Adjust the bench so that your waist is in line with the top of the pad and position your feet firmly on the platform. Bend at the waist and lower your body towards the ground until you reach about 65-75 degrees. Pause briefly at the bottom and then raise yourself back up to the starting position where your back is in a straight line with your lower body.
Tip: Focus on keeping the tension on your lower back throughout the entire motion. In order to add extra resistance to the exercise you can hold a weight plate against your chest.
