That video really proves a point a lot of the internet trolls and twits don't get. I post videos of myself hoisting some pretty decent weights with decent form and get jumped all over for it, yet I look better than 99% of those criticizing me and am significantly stronger. The perfect form twits just don't get that the biggest guys almost all use a looser style when training whether that be in the form of partial reps, some body english, or the the like. Watch a video of Ronnie, Branch, just about any really big guy.
There is nothing wrong with "perfect" form, but if you want to be really strong to go along with the looks, you need to train in a touch looser style.
