Believe it or not at age 6, here's the kicker though; NEVER make a child under the age of 15 "feel the burn." Taking it to the point where the muscle begins to burn, should only be done at age 15. Even then, at 15, only a moderate burn, and the burning sets taken to progressive intensity to high intensity only by age 18. Now, if its calisthenics, you can train a kid as hard as you want and nothing bad will happen provided they are not overtrained; literally thousands of boys in strength based sports such as American football or Wrestling do cals and they grow tall just fine. However high intensity weight training, it has made more than one dude with a tall father shorter than he should be.
Weight training is fine for kids but NEVER take it to the burn; you want to use light weights, and take it JUST to the point of fatigue, the half way point between the resting phase of the muscle and the burning point, that is, to the point where blood flow to the muscle is felt but NEVER tear up the muscle fibers. NEVER, EVER, force a child to "feel the burn" while lifting, its dangerous, very dangerous. Any strength coach will confirm what I just said here.
You can lift wights at any age you want in private, but in places like gyms and sports centers expert trainers say you should be 15-16+. Although a 12 year old could lift weights, their arms and bodies aren't fully grown. Although they look alright on the out side they could cause damage on the inside.
I would wait until your in junior high or 7th grade before I started to lift heavy as your muscles just aren't ready before that.
theres 1 thing that i do before i attempt one heavy lift. I lie to myself about the weight, saying something like " ok i just did this for reps yesterday its easy".
mabey, but it really depends on his weight.
It is ok. When you start training a dog to pull weight, a heavy weight from the begining is not good. You should start with a light weight and work it from there.Update: I finally found a link to put in this question in the related links box below.
it's ok height
You need to be about 12. but its ok to start a little younger than that.
if its cargo van load range E IS A HEAVY DUTY TIRE FOR WEIGHT
This would be an unusually high weight for a 12 year old. The average weight range would be anywhere from 85 to 105 pounds.
See related q:What is a normal weight for a child of a certain height and age?
I think it should be OK as long as one says sorry afterwards to all in the lift...
your weight is ok but for your age its a little low.
She is not a wrestler but yo mama's so fat that she went to a restraunt, looke at the menu and said "OK!!". She also had to go to Sea World to get babtized.
It's not your age that determines your acceptable weight, but rather your height and muscle to fat ratio. If you are tall and lean, 250 pounds is ok.
