I dare not say how to lose weight. See if you jump 500 times or take a break. Try to sweat every time you exercise. Generally speaking, aerobic exercise will last more than 40 minutes to be more effective. If you consume more calories than you consume every day, you will lose weight.
Bouncing can really help leg muscles and stimulate all joints, but jumping alone may not be enough, which may easily damage the knee joint. It is suggested to combine in-situ jumping, stretching, frog leaping and leg lifting. Don't underestimate the role of lacing. Good ties and body shaping will also help you grow taller.
In the process of exercise, diet is also very important, such as adding more cartilage (growing taller) and protein (eating less when you are full), eating less fried food, and having a fixed routine, so that your body can grow taller rather than develop horizontally. Stick to it for a while and exercise will have an effect.
