If Vince was as smart as he says and thinks he is,he would lose all that excess flab first,then try to gain muscle, or do both at the same time instead of just trying to get bigger.
You are plain old fat, and any size you have is just added to your already fat body, so it`s almost damn near impossible to tell how much is muscle,if any,and how much is just more bodyfat.
Eat clean,train your whole body with moderate weight,less rest between sets,and eat clean food,with plenty of water.
How simple is that,not very simple at all because it takes a lot of consistancy and dedication............. something I think Vince is lacking in bigtime.
Any idiot can work arms and eat like shit, but try training 6 days a week and eating clean..........almost impossible for tons of so called bodybuilders.
Pellius would have easily beaten Vince in 1970 if he looks like he looks today and Vince was in his Mr. Canada condition.
