first of all you cannot bench 308 stop lying to yourself and for your answer 135 or above
they say you should be able to bench your own weight but if you have been training for awhile your muscles will let you bench a lot more than your weight.
a 16 year old should be lifting in his bench press around 150 and 200 pounds, if you bench within these numbers than your in pretty good shape. But if were talking about squating it should be around 200 threw 250 pounds , but most 16 year olds barely squat as much as bench.
easy

If your strong 50 lbs.

i think that he should start off with 100 lbs but in the end, he should be able to bench 200. some where near his weight.
If your in good shape you should be able to bench you weight, but keep in mind that is a 15 year old that is in shape.As far as arm curls go, I would say 40lbs.
90 lbs

Most 5' 12 year old's should be able to bench a little less then there body weight. There muscles and form would be highly underdeveloped. This is also only true if the child is of healthy weight.
