Thin people really need to eat more to gain muscle, and their calories and protein are also high, but they don't have to wait until they gain weight before practicing. Let's begin. There is no direct conversion between fat and muscle. In other words, fat will not become muscle, and muscle will not become fat. To some extent, these are two unrelated things. If you want to exercise your muscles, you don't need to eat fat beforehand.

If you are born thin, the most important thing to improve your figure is practice and diet. The focus of thin people's training must be the increase of muscle circumference. Therefore, the training method of increasing skeletal muscle should be adopted. Someone once said, "If you want to exercise muscles, you must eat fat first, so that you can have enough energy." . Fat and protein can be transformed under extreme conditions, but it is too much to think about here. Fitness will not turn fat into muscle, and muscle into fat.
