172 lbs of muscle in a year? yeah..... right......

you mean 96... but still humanly impossible

I agree with jjroder. Nathandegrave hasn't a clue what he's talking about! Putting on 172 lbs of muscle in a year is a feat that is only done with the help of steroids.

lol, nice maths skills bro

Alright guys... My guess is that he just started working out and the rate at which he gains was spiked or still is spiked while he wrote that comment. Once he's been in the game for awhile he'll learn a little more. So Nathan, for a pro... who is already pushing the edge of their limits... that kind of gain is very impressive. After you've been training and such for about 2 years... you'll have a little more understanding of that. Don't let these guys discourage you.
