Many folks say that if you want to build muscles, you need to have fat before you can become muscles through exercise. If you are too thin, you can't build them. This statement has spread widely and misled many beginners.

First of all, fat and muscle are two completely different substances. The former is mainly composed of fat, while the latter is protein. The two substances cannot be transformed into each other. Make this clear, and the answer will be clear. For thin people, you don't need to eat fat first if you want to gain muscle and shape.

Practical fitness experience tells us that losing fat is often more painful than gaining muscle. People born with a lot of fat need not only hard strength training, but also a lot of aerobic training. If you want to show beautiful muscle lines, you must strictly control your diet. But for people born with low sebum content, just concentrate on training, pay proper attention to diet and do aerobic exercise properly.
