Weight lifting is good at any age. However, before the age of 18 the spine is still very malleable . Therefore any spine compressing exercises (dead lifts, heavy squats etc.) should be avoided.
Unless you think you may look like this; But it hasn't stunted his growth; Nor has it stunted his popularity;
Depends on the kind of weights you lift. Weight lifting will never actually "stunt" your bone growth. However, lifting improperly or too much can result in injuries or pressure on certain areas of your body (the spine and the knees come to mind), resulting in your bones growing in ways that stunt HEIGHT, not growth.
It sounds reasonable- it's not actually true, though. Just think about it. All weight training really is is manipulating external objects, which is something you do all throughout childhood and adolescence. Or at least most of us do- anybody who didn't try carrying his dad's toolbox as a 6 year old is a softie.
Agreed. The only time extreme muscle mass with weighted resistance is added is when a little thing known as testosterone comes into play after puberty.
