Hey Brad,
Glad to hear you enjoyed the book. That bicep move makes all the difference, doesn't it? As with any exercise, it'll go stale after a month or so. Do it until it stops producing results, at which point, take a break, and come back to it a few weeks later.
Since you say your legs suck, you're going to love the "4 minutes a week" calve workout. People tell me they can't walk for days afterward!
Concerning workout frequency: 4 workouts a week, 2 muscle groups a workout will cover the entire body in one week. Work a major muscle and the assisting muscle group, i.e., chest and tris, back and bi's, quads and hams, shoulders, traps and abs. (Calves can be done with legs, shoulders or on an off day -- hey, it's only 4 minutes!)
I never do the same workout twice. Nothing magical. That's just the way I like it.
Protein requirements? I think you should re-read the diet chapter. I'm pretty clear on that.
Don't expect anything from the 1-AD. You will get results from the exercise techniques I outlined though. Get a refund on the 1-AD, and use the money to buy a couple of thick juicy steaks.
