Alexander Karelin is, in my opinion the toughest man who ever lived. He was a Russian Greco-Roman Wrestler who went undefeated for twenty years. His feature move (seen above) required him to lift a man (usually in excess of 300 lbs.) up from a prone position and flip him over his hip through the air until he landed head first on the mat. Many of his opponents would walk on to the mat and forfeit rather than be thrown around like a rag doll. And talk about intensity and focus. No MMA fighter would phase this guy!!!!!
