Load a barbell with a ten-pound weight on either side and place it on the floor. Position your hands about one shoulder width apart on the barbell and kneel in front of it, like you are on your hands and knees (except your hands should be on the barbell, not the floor). From this starting position, slowly roll the barbell forward across the ground until your body reaches a straight position. Ensure that you do not allow your body to actually touch the ground at the bottom of this movement, as this would take tension off of your core muscles. After briefly pausing at your maximally stretched position, begin to slowly pull the barbell back towards you until you are back into the starting position. Repeat for the prescribed number of repetitions.
