Somewhere in the gym must be a matted bench that can be put on anyone of about four metal racks. Handles are on one end of it.
Place the bench on the highest rack. Grab the handle with both hands. Your head should be on the side of the bench with the handle. Keep your neck ad chest relaxed and your back on the bench. Raise your legs by using your lower abdominal muscles as much as you can use them. Raise your buttocks off of the bench about half a foot. Do four sets often repetitions. Increase to five sets of ten repetitions when you can, preferably within a month after doing this exercise on time a week.
