Is it possible to increase height for a 17 year old male because there are documents that suggest it's possible. Is there exercises that might help?
No. If your growth plates are no longer open, growth is over. Typically by the time a boy is 17, the growth plates are near complete fusion. There are no height enhancing exercises. If a 17 year old boy has delayed puberty there may be some growth potential left as the biological age would be younger than 17.
