Eat more fruits and vegetables that can reduce swelling and diuresis, such as wax gourd. If your face is fat because of huge muscles, please refuse chewing gum, sugar cane and other foods that exercise your chewing muscles, because they can only make your facial muscles stronger.
It has nothing to do with sports. It means that your physique has improved. It is normal to have a fat face. Your body is gaining weight, and of course it will be somewhere else. If you have too much meat on your face, it's your own problem. You can buy face-lifting cream. If you don't want to, you should pay attention to your diet. But exercise can't give up. Eat less foods with high fat content or things with high protein content.
It is also possible that your face does not sweat easily, or your face does not sweat during training. Generally, in the case of weight gain, the face will increase, but it will not be very big. Only in this way can there be a sense of overall coordination. It is normal not to be too fat. Never mind.
