If you want to talk about ARMS, Robbert kills both of these guys.His arms off season were up to 24 1/2" when he was 315 lbs.They were OVER 23" on stage!!!!.This I know because Lonnie Teper had some girl measure them.Robert is an ex strong man.He has only been bodybuilding for 4 years.He has only done 5 bodybuilding shows.Give him 2 years and he will kill Zack Khan, this I know.
Robert really didn't know how to train or diet for a show until 4 months ago, when I met him.
Now that he has help, and he is learning look out !!!!!
If you look at the pics of the USA's of Robert, and compare him to the Nationals, he doesn't even look like the same person.In 4 months he made more improvements then most guys made in 4 years.
Just Imagine if Robert has a really good off season, and brings up his weak points, and backs off on his arms??? Zack Khan is a friggin house, and a good athlete, but so is Robert.
