Ahhh, ab exercises. I wish I could tell you that I have the solution. Sadly enough, I'm looking for it myself. I can't do regular crunches, but I can almost manage knee raises without too much problem. I do some half-assed crunches at home, lying on a mat with a thick pillow under my upper back, so that my starting position is "mid-crunch" and then I just tighten my abs really hard (withouth actually doing much of a movement). It seems to work...kinda...but yeah, abs are hard to train.
I get that comment about my distaste for programs, plans and recipees a lot. I love to cook, but I never ever go near a recipe. I'm an organic, synthetic chemist and most of my research is explorative. I just test a lot of stuff and write down my findings
