Stand in front of a barbell sitting on the floor and bend over and grasp it just wider than shoulder width. In the start position, the knees are bent and the back is flat and parallel with the floor. From here, pull the bar off the floor and up to your midsection without lifting your torso or extending your knees. When the bar touches your midsection, slowly lower it back to the floor, letting it rest momentarily before the next rep.
