When I first saw the workout I thought it was too much and didn't do all of it. But then when I wasn't getting big gains like I had heard people were getting I started doing all of it. Lot's of times I do one less set than it says to do. I'll skip the first step and just do the last 3 or 4. It is very rigorous and tiresome so I wouldn't doubt for one second that I'm over training.

And yes of course, I'd be interested in your diet. I need all the help I can get.
