North Korea's Kim Un-Guk set a new overall world record in the Men's 62kg (136 lbs) Olympic Final at the London 2012 Olympics. He got a combined weight of 327kg (719.4 lbs), beating the previous record of 326kg set by China's Zhang Jie.
Both lifts are more than twice his body weight, and the clean and jerk is nearly 3x his body weight. Seriously impressive.
