This is all funny, because I think you guy are all lying.
children your age, without sports or training is like 6-8.
I'm 15 and weight 124 pounds and I bench 150 and I can only do 45 push-ups in a row, I've been training for about a 1 year also and your probably not even doing them right if you have "100" or "50".
This is just kids trying to show off and be people that they really aren't in reality.
