There are a lot of different kinds of crunches and abs workout out there. I like to do a variety, to keep my muscles confused. If you do the same exercise over and over, your muscles get used it it, and the exercise is less effective.

Click the links I had n my previous post and look under the "abs" heading. Remember that there is more to abs workouts than crunches, as there are several different muscles you need to work, and crunches don't work them all.
