Reverse Crunch
Support yourself by holding bench or placing hands beneath bottom. Keep legs straight and raise them to a 90 degree. Once at top, crunch knees to chest. Un-crunch back to 90 degrees. With specific focus on keeping your stomach flat(do not let it round out, hold it in), lower legs to starting straight position. Repeat!
