Let's talk about losing weight first: Sixth-grade boys should not care too much about losing weight, because losing weight consumes more energy than taking in, but when you grow up, you need energy, so you won't grow up without losing weight.

In addition, playing basketball: I don't recommend that you play for two hours every day. Many NBA stars have worn their knees. Obviously, the more exercise, the better. Scientific research shows that it is best to exercise three or four times a week.

Finally, how to lose abdominal fat, 100 sit-ups every day is definitely more useful than playing basketball for two hours. It will be difficult at first. You can do 10 in the morning, 10 in the evening, and then add it bit by bit. If you stick to it, you will not only lose your stomach, but also have six abdominal muscles.
