Of course I didnt do a 500 lb bench press when I was 18. Nice try genius! That's not the point. With strict form he's only a 400lb bencher plain and simple. Take away the steroids and he'd probably be benching around 350. But you've got shit for brains so I dont' expect you to understand how those factors come into play.
Lol, you are the dumbest guy in the world.... Well, maybe not the dumbest, but you are in contention.
First, you have NO CLUE how much the arch adds to his bench. Do you know ANY world class strength athletes? Have you ever trained with any? NO!!! You don't know shit about that young man and your comments are jealousy pure and simple.
Oh, and just an FYI, he can do a lot more than 400 lbs with no arch...
