Muscular Potential and Fat Loss - Lyle McDonald

Many of you no doubt have read Lyle McDonald. He is a very well known sports guru...doctor. I find his research to be pretty good. With that said, I'm trying to boil down all of the essays found at: http://www.afboard.com/forum/showthread.php?35747-A-Thread-Full-of-Lyle-McDonald-Articles/page3 and how it pertains to Muscle potential and fat loss.

Specifically, if you read posts #73, #74 and #91, what it seems to say that all things being equal (diet, training, genetics, recovery etc), that the average weightlifter/bodybuilder (assuming not a teenager) would do best to first concentrate on building muscles for the first 3 possibly 4 years. At that point, the majority of one's muscle gains have been captured. At about year 4 or 5, you could then switch over to becoming lean/cut.

He goes on to explain that you should do minnie bulks/cuts. That most bodybuilders (not pros, just gym rat types) should stay within 8-10% BF, bulk up to say 12% and then cut back down.

I realize I'm summarizing this big time and that this is for the "average" gym rat, not the genetic (and possibly chemical enhanced )superior pro.

Thoughts?
