Increase exercise and stick to it, and eat less foods with high protein, fat and calories. I only ran 1200m in the morning. I think it's jogging.

1, get up every morning 15 minutes to run 3 kilometers, and do gymnastics properly in the rest of the time.

2. Before you rest at night, do 100 sit-ups, 50 at each end, and connect them end to end for 5 minutes! Massage your abdomen and relax your muscles after you finish.

3. Don't sit for a long time when going outdoors during recess.

4, do not eat fat, do not eat snacks, do not eat beans, it is best not to drink milk properly, eat whole grains three times a day, bid farewell to snacks, potato chips, French fries. (Practice from end to abdomen, lie flat on the bed, keep your legs together, straighten your toes, and raise your legs above 40 degrees, not too high. Hold on for 2 minutes, and then hold on for 3 minutes.) Remember not to drink water immediately after exercise. Once you drink water, you will fall short!

Sports is about persistence, as long as you persist, you are invincible! I hope I can help you!
