Utilise the specially designed shape to isolate the abdominal muscles and get the full range of motion, resulting in more effective sit-ups and crunches. Sit-ups are hard enough without worrying about pain from the floor. The Force USA Ab Mat prevents back and tailbone discomfort by maintaining a neutral spine position, supporting your lower back and taking the focus off your hip flexors so you get maximum burn in all the right places.
