My 13 year old brother wants to start strength training with me. I have read before that this may not be such a good idea as training with weights at such an age can impede normal growth and development. I don’t know if this is true or a myth.
I am inclined to encourage him to stick with playing sports for the time being and maybe introduce him to some body-weight exercises such as pull-ups and press-ups. I would be interested to hear your opinions on the best types of exercise for people in this age category, particularly from any physical education teachers or anyone else who is involved with training young people.
Thanks for your help.
