Yep two totally different versions of strength imho. Some body builders focus on only a selection of muscles that allow them to perform their various lifts and get big. The guy you linked works every single one of his body muscles in equal proportions which means he can do pretty much anything and know that his body will be strong, no matter what muscles he calls upon at the time. I'm too much of a lazy bum to even try.. but if I could have either body, I'd have Jan's.
