When I did BFL 2 years ago, I found I got much better results when I
did cardio every day and did upper body one day and lower body the
next. You get 3 upper and 3 lower workouts each week. That way, I saw
results MUCH faster instead of only 1 upper body workout a week.

I think the key that was not stressed enough in the BFL book was REST!
You have to find a way to get plenty of sleep at night so your body can
regenerate.

Just my 2 cents.
