In fact, for your height and figure, you are relatively fat, but if you can keep playing, you will definitely lose weight. Let me give you some advice. Eating habits should be regular, don't overeat, don't drink more beer and drinks, it's better to drink water and don't eat a full meal, around noon, about 7 dinners. It is good to play basketball about 2-3 times a week. If you don't play basketball, run or do some other sports with less exercise. With your present size, you have played basketball for many years, and there is definitely no technical problem. You just can't find your hands or your body can't adapt to it for a while. You can shoot more in the second half without overdoing it. Now you are recovering to find your own feeling. Then the playback position needs to be changed. Now you need to get used to playing center, because your figure and height are ok. When you get back to your desired state and body shape, you can consider playing back to your previous position. After a month or two, it should be able to recover! Hope to adopt, thank you!
