what is the height that you desire for yourself?

4cm is quite achievable since you only 17.

well.. im not expert in growing height, but you might wanna try to eat some calcium dense, bone strengthening food , such as broccoli, spinach , maybe milk? and get sufficient vitamin D by expose to sunlight at least 30 min a week.

obviously, jumping exercise is going to help you growing in height more faster, but i highly recommend you try to do yoga, stretching is good for your overall body.

so, eat good, exercise well, and sleep well, and then just let the body do the work.

i wish you all the best
