At the age of 20, exercise is indeed a necessary condition. After all, it belongs to the second half of growth and development Sports focus on jumping and stretching, jumping first and then pulling. Of course, we should also strengthen diet and nutrition at ordinary times. You can eat more foods rich in protein and vitamins, supplement trace elements such as calcium, iron and zinc in time, and do sports such as playing basketball, badminton, cycling and running. It is better to do exercises systematically. Long-term persistence is helpful to your height. Now I touch the height 60 times in a row every night, and then stretch for nearly 40 minutes, including leg press.

I read the exercise method in Yang Yunfeng's diary. It's been two months, and it's increased by 30 cents. I am 2 1. Keep going! Never stay up late and keep a balanced diet. For example, if you eat fish today, you can switch to pork tomorrow and chicken the day after tomorrow. If conditions permit, this arrangement can be made. According to your growth plan, keep exercising for three months, and it will be effective. Of course, it depends on personal circumstances, and it will take half a year at the earliest.
