No doubt that Lee Priest is one of the most giftest genetic specimens in BB history. I would die to look as good as he did at age 17 while being supposedly natural. We can argue all we want about whether he was natural or not. I think it's possible, but not for the average guy. All the good diet and training in the world will not get you to where Lee Priest was at 17 without the genetic gifting.
Just use his physique as a motivation to improve yourself and attempt to maximize your own potential, whatever that may be.
For example, for me, I'm too thick in my waist and hips to ever have that amazing taper that the best guys have. It still looks pretty good, but I could never be world class no matter what drugs I took, or what my diet or training were. I've got the genetic make up to be a good fullback, but for the lack of speed and skill, LOL.
I bet if you asked Lee whether he was happy with his amazing God-given genetics, he might say he wishes he were 6 inches taller. As for me, I wish I was 6'2" and handsome. Oh well....
