I sit back as far as I can and do eight regular curl-ups, then eight twists--alternating sides, sometimes double on each side for variation. When I reach burn-out, I stretch my back and shoulders out, then do it again. I'm still just using the 12 lb. medicine ball and the third notch on the bench. Also, first you should mark your form with your hands behind your head, shoulders down, elbows to the side, look up and breath out as you sit up.From what I gather and have been doing you do the twists while in the up position. Your back should not be touching the bench. It's more work to stay in the up position while twisting as opposed to lying down and twisting.
Of course this wouldn't be the first time I'm completely wrong about something.
