I am 19 years old , my height is 5" 8" ,weight 65, everyone in my family is tall , my brother and my father is 6 ft and my sister 5" 7" . I am the only short person in my family. I want to join a gym for body building , will this stop my height growth ? Upto what age can I expect my height to grow ? What exercises can I do at gym which does not stop my height growth . Can I expect my height to grow even now or should I join the gym freely . I don't have much beard may be because my puberty is not over . Please help.
