We usually thought that weightlifting is a tough game. It is only for great physique.
There are 6 man in history who lifted 3 times their body weight. Check here.
3 of them are Bantamweight(56kg), 2 of them are Featherweight(60kg), and 1 is at Lightweight(67.5kg).
All of them are light. Is there are fact that light weighted are more efficient in weight lifting?
