How much should an 13 year old squat?

im 6ft8 and play College Football at South Carolina wiegh 315 at o line and squat 675 but at your age about 145

It, like the bench press, depends on your weight. I started lifting at 11, and I'm 12 now, turning 13 in 13 days :). I am 5'3 right now, but I only weigh 90 or so pounds... It wasn't until this past summer that I really started to work on squats. Even when the school year started I didn't really have time because I wrestle, and so I focused primarily on the bench press. Recently though I've been working hard, and I can squat a max of 170-180... It depends on your size, some bigger 13 year olds can squat over 200. I'm in the 7th grade and hope to squat 200 by the end of the year... For the average joe though, 120-145 would be good for a 13 year old.
