don´t worry brother, When I was 14 I was about 165cm now I´m 183 at 17 and 1/2. You have a lot of time to grow, to be precise five to six years, you´ll grow until 19-20 years old. Here a few tips:
1. sleep 8+ a day
2. don´t eat any food 2-3 hours before you go to sleep
3. start exercising about 3 times a week. you can hit the gym or do calisthenics
4. eat healthy nutritional food (watch some youtube videos about a healthy diet that maxximises growth)
just live a healthy lifestyle to maximize the human growth hormone, which is responsible for your growth.
5. special tipp start sprinting: it increases human growth hormone by three or fourfold if you sprint correctly. It isn´t important how fast you are, but rather how much effort you put into it and how close to failure you can come
my routine is:
20-30 seconds all-out sprinting
90-120 seconds rest
and repeat this process 8-10 times for maximum results. And this one workout do 2-3 times a week
