Generally, 13 year old children should not be lifting weight. It has been known to halt or alter growth. However, that is not always the case. For those that wish to lift weights, 10-15lb weights are good.
I can lift 45 to 55 pounds I work out a lot.I think a 11 year old boy should be able to lift 25 to about 30 or 35
More than you can that's for sure
An eleven year old boy should have 2,300 mg a day
It all depends on genetics. Based by your weight you may not have much muscle, but if you can lift your weight or more you are in good shape. On avg a 112 person can lift around 70-90 pounds.
There really is no specific limit to how much a fourteen year old boy should weigh. It depends on how tall you are, because if you were 5' 9", you should weigh more than a fourteen year old boy who is 5' 2".
