Eclypse, you sound like you've read Core Performance?
I'm not much of a reader, to be honest. I've been to school for Exercise Science for two years and been working as a personal trainer for two years as well. All the stuff I said about "inventing" what I call a "back crunch" is simply logical application over time; I know other people have realized the same thing, but it's just not mainstream exercise knowledge. That's the nice thing about my job; I work at a YMCA where I can be more concerned with health than the hotness of my client's body.

But, how then do you explain how crunches are frowned upon on the S&P forum these days, vs using weighted situps. Just a thought.
I don't know exactly why the people in the S&P forum don't like crunches; I don't tend to read over the old stuff so much as answer the new stuff. I don't really have that kind of time.
Anyway, my theory on why people wouldn't like crunches is because most people just do body-weight crunches, which lessens the strength stimulus once you're strong enough to do more than 16 reps nonstop. I do my crunches on a selectorized machine, which allows you to add weight directly to keep up the proper repetition range for strength and size. Also, crunches don't have the most common, everyday practical applications. However, for MMA purposes, they are excellent for building size, which means they provide better armor as well.
I think people should do an equal amount of crunches and situps, really. Situps are good for developing the hip flexors but not so much for the abs. It's hard to do a high-efficiency oblique situp, though, so crunches are necessary for the obliques.
The big problem is that people get their information from magazines or hearsay. Most magazines, like most people that offer you advice, are more concerned with impressing you, getting your attention, and in the case of magazines especially, getting your money. I'm pretty logic-minded, so I figured rather than trying to sort out all the garbage you get from magazines and hearsay, I would go study. Honestly, you could pick up a Personal Training Manual, from ACE or NCSM or NASM or someone, and get some great clarity from that. It'll run ya a few bucks, but isn't it worth it in the end?
