Hi, thanks for using health care magic
Unfortunately it is not possible to increase height at your age, in general most person will stop growing in their teens after closure of the growth plate.Finally height is determined by majorly by genetics and in some part by enviromental factors such as nutrition, history of chronic or recurrent illness and physical activity.
Though your final height cannot be altered , some persons recommend doing yoga
and pilates exercises which may strenghten the core and result in better stature.
In terms of general physique this can be altered by cardiac exercise training and strength training exercises.
I hope this is useful to you
