Hossein Rezazadeh is the world's strongest powerlifter....and most would argue (myself included), that he is the strongest man who has ever walked this planet.To get an idea of this man's strength I have posted a link to him setting a World and Olympic record Clean and Jerk at the Athens Olympics 2004.

To put this lift in perspective you must first realise he is lifting 580-pounds (263.5kg). Secondly, you have to realize that he cleaning it.....then jerking it over his head. Cleans are much harder than squats....it's like a double squat. Very strong people have trouble with 135lb cleans. I don't know many people who can actually clean 135lbs.....let alone jerk it overhead.
Anyway, I suppose the point is that power lifts can build supernatural strength....for people from all walks of life.
Ciao for now!
