To suggest a man weighing around 300 pounds squatted to appreciable depth with 900 pounds, and without massive support gear, is to expose one's ignorance. As has been said, the greatest strength athletes in the world would be crushed under such a weight if they were to attempt such a feat raw and to "legal" depth. Captain Kirk hit a mid-sevens raw squat several years ago and he is one of the legends of powerlifting, known for his ... squatting prowess.
It's ignorant buffoons like you who perpetuate nonsense and stupidity.
Captain Kirk hitting 1000 for a double.
INSANE.
