There is no evidence that weight lifting stunts growth. In fact, bones can become stronger from the exercise. Science has proved that weight training will not stunt your growth even if you start at as young as 10 years old. The real danger is if your not supervised and have bad form injuries may occur.
Nick Scott became disabled from a car accident when he was just 16 years old. Afterwards he went back to weight lifting after a bout of feeling sorry for himself. He won his first weight lifting award in 2001 before his accident.
it depends on how heavy u are lifting and how often, i have been weight training since i was 10 years old, along with running and rugby. my muscles r alot mur developed than my friends and allot stronger. you must make sure that you are doing low weight but high reps. e.g start on a low weight that's right 4 u and lift 15-20 reps. and as you get older you can start getting higher weight lower reps like me. goodluck
You should start weight lifting at the age of 12. At that stage your going through puberty and you can make muscles easier. But you should only do 10-30 pounds depending on your weight and height.
I'd say start lifting now. A good mix of both Strength Training and Cardio, along a good diet is the best mix for weight loss and overall fitness.
Arnold started weight training at the age of 14.
Boys generally start taking an interest in improving their bodies about the time they hit puberty (12-13 years old).
