Lifting weights and doing cardio will never stop your growth it will actually help it. The hormone (GH) or Growth Hormone is produced from lifting weights because you are triggering the pituitary gland to produce the hormone from the exercise. Same goes with cardio. working out in the gym or running will not stunt your growth.
Yes, this is old enough. Lifting will not stunt your growth as the myth grows. Just make sure you do it correctly, and get supervision at first.
No, it does not stunt growth. The ends of the bone are still growing when young, and some people thought that if the bone was broken your growth would be stunted, but this is undocumented. Lifting is very beneficial at all ages.
Yes, a 15 year old can lift weights with high intensity and not stunt his or her growth. Studies have confirmed that this is a great age to start exercising to this extent.
Yes and no. It can have a negative effect on your body's development. Serious weights training should not be started until the age of 18 or with the advice of a doctor. But, if you do light weight sets, 2-3 times, with no more than 15 reps, then that is okay.
NONE! A nine year old boys body is still growing so he should wait until he is at least 15 until he starts lifting weights. If he starts any early it can stunt his growth
That;s an interesting question. I am happy you asked this. I am a major science wiz. I am 15 years old. I recently had a theory that weight lifting could improve growth if done properly and safely. I started weight lifting when I was 14 years old. One thing to make sure of is to lift weights your body can handle and weights that are not too light or way too heavy for you. I was lifting some heavy weights. Though I still grew an inch TALLER! I was 5'8 and grew to another inch over the summer. I am now 5'9. My shoulders got wider and stronger. My chest also got bigger and harder as a result of weight lifting. But doing weight lifting wrong can damage your growth plate and stunt your growth in the process. It won't stop but it will slow down as a result of damage. So if your doing it or want too do it. Then I suggest lifting weights good for you. Make sure you have an adult who has weight lifted before has more than enough experience with weights. Weight lifting is very good because our muscles need that kind of stress factor in order to improve in performance wise.
obviously each individual is different, but for some people 15 is the minimum age to start, 16 for others.
within the first 15 minutes
No. It may increase your growth due to release or uptake of extra chemicals in your body, which you don't want to do. It will however likely deform your muscles. I started at 14 and I have a slightly deformed left arm because of it. Wait until your 15, or lift light weights only.
