Yeah, sad there aren't any intellectuals here. What, with you being able to spell "infinate" and all.
Oh, and man, shut up. Seriously, you can't argue with results and there are people who will swear by cable crunches alone to develop abs. Or static contractions, as d3 said, or V-Situps or other shit. Personally, I feel the bicycle exercise is useless, and makes you look like a jackass. Go on with your little maneuver, but don't argue with results. The abs are a muscle. The muscle gets stimulated, it grows to adapt to a heavier load. Much easier to add weight with crunches, as far as I'm concerned.
