Stay out of this thread... will ya? you have no clue... Zack is already one of the biggest... he has NO gut... NO blocky waist... no real obliques and his muscles look young, vibrant and full... if you havn't noticed his appearance at the British Nationals. Zack may need a few more pounds on selected body parts and a bit more polish... that's it. He doesn't need 20 or 30 pounds... hence he won't develop a gut. He's already way over 300 lbs off-season and has zero gut on stage... go f-k urself rice eater... 
He will eventually get a gut, as do all of the bigger guys. Look at Ronnie in 2001 vs. his earlier years - he was lighter in 2001 but his gut had begun to grow regardless. Because Zack is a newcomer he won't get top contest placings for a few years until he "pays his dues," and by the time he does "pay his dues" his contest placings will improve but his gut grow, and eventually fans will look and say, "He looked better in 2009 than he does now, why is it that he is placing better now than he did in 2009-2010?" The judging that goes on pro shows is a joke.
