Regular sit-ups hurt my neck before my stomach (I have had a trainer look to make sure I was doing it right...and I was) so I found out about bicycle sit-ups which I am able to do without my neck hurting (and I found it to be more beneficial so far). Anyway that was some background info...I am a slim guy and I do have a 6-pack if I flex pretty hard, but I was wondering about how many bicycle sit-ups would take a day in order to not have to flex at all for a 6-pack. (I know no number is fissure, but what would be a well *educated* guess?)
I don't care about losing weight (if anything I need to gain weight) I want a 6-pack without having to flex it.
