Too much scientific knowledge is bullshit. Let me tell you the truth. If you want to lose weight through badminton, first of all, you should love badminton and be exhausted, chasing yourself like a donkey, a ball and a carrot; Second, you should have a certain level, that is, you should run before and after the game. It's one thing to see the ball catch in the backcourt, and it's another to run or not. Women don't want to play mixed doubles and give most of the balls to men. Men don't want to play doubles, which saves effort. It is better to have scores, scores and motivation. This kind of beating yourself for three hours a day for a month seems to have broken tendons in all limbs, and you can't lift your hands and feet, so that you can lose weight. Can you really do it?
