The best way to lose weight at this age is to jump and run, which will stimulate the leg bones to grow taller and taller. You need a lot of calories. Haven't you ever heard of "half-grown boys eat me to death"? Teenagers at this time are at the age of eating, so don't consider losing weight. I jog for 5 minutes in the morning and evening to warm up, then jump 10 times, and then simulate shooting practice to give a certain impact to my leg bones. When I am tired, I take a rest and practice jump shots for 7 to 15 minutes to stretch my leg muscles. Exercise properly, don't get hurt or tired, eat more meat, eggs or tofu, and talk about other things when you grow taller.
