Hey Drew, went through the book last night. Looks pretty intense...Did you/Do you still follow these exercises? I can see what you mean on how you'll be really feeling it...
Yeah, I still do it, but I never have done the entire program through and through. I originally was going to, but in the end, I got viewable results so quickly (honest, I really did, you should see SOMETHING within 2 weeks of following it on their recommended schedule) and slacked off. All I use it for now is to help ward off any serious back problems. What I do is mix up stuff and do it twice a week as kind of a "maintenance" program, and as you've seen, there's only one that involves any "special" kind of equipment, so there's really only 6 exercises.
I kind of averaged 'em out for what I do now, and I just pick 2 to do for that day, and a different 2 the next day, and so on down the line for the other remaining 2. With only 6 exercises, it's pretty easy to keep up with what you did/didn't do.
I do: 25 standard leg raises - 15 advanced leg raises - 30 cramps - 20 cross knee cramps - 15 quarter situps (ALWAYS do these fast. Slow or medium speed always seems like it's ineffective) - and 15 rock-backs. Once a week I'll do 25 hyper extensions
It's really not a six-pack building regime, just something effective to help with back problems. There's a MILLION guys who look to be in the same shape as I am. I don't know of any of 'em who don't have back problems after some hard work, so either my tolerance for pain is higher than theirs, or these things help stave off the problems they're currently having. I prefer to think it's a combination of both.
I think your fooling with me though...right
, you doctored up the book with your Photopaint skills there and added in the one that is intended to kill me right ?....Gasp!
Take me a while to work up to this one...After I purchase the flying trapese 
I used to do these, and I sometimes throw them in on my Soloflex, but I always feel like I expend more effort into maintaining my grip, rather than the exercise itself, and I can't do as many as I feel are worthwhile. If you want to give these a shot and you have a basement, here's what I orginally did. Go to some sporting goods store and pick up a chinup bar. In the basement, screw it to your floor joists for upstairs. I had to cut a notch in one of the joists, but it worked just fine.
Once you get over the period I told ya about, you'll find these really easy to follow/maintain.
