I think it's possible. For a person, fitness is not simply to make him lose weight, but to make her stronger. If you are fat, then fitness can help you lose weight. If you are thin, then fitness can help you gain weight. Therefore, I think the channel of fitness is to neutralize a person's body, that is, to make you look stronger and healthier, so I think thin people can gain weight through fitness. Moreover, fitness and weight gain are definitely good for yourself.

The main way to gain weight through fitness is to increase muscles and then make yourself look stronger, so I think this kind of weight gain is much better than eating some good things, then accumulating fat in this way and then taking diet pills. You will find that you will become particularly healthy and have more spirit to deal with some things through fitness, so fitness is really a very good help at this time and you can get some more quickly.

When you exercise, eat more foods containing protein, because only by eating more foods containing protein will your muscles grow faster, which will be of great benefit to you. After that, you can grow more muscles in a short time, so I think protein is really important at this time, so this hand must remember to eat more food containing protein, such as fish, shrimp, frogs, and beef is also a very good recommendation place, so I hope everyone can pass the fitness.
