Emphasize that the arms should be thick. You should know the fact that only when the muscles are thick can the arms grow accordingly. Therefore, it is necessary to practice all over and carry heavy loads. It is king to practice squat, hard pull and bench press in training. This is the trump card for gaining weight. Considering there is no gym there, I suggest you go to the store and buy a barbell.

If you don't know how to do it, push the squat hard and push Baidu, you will understand that bench pressing is not convenient. Instead, push-ups (load-bearing) are used. Your muscles will soon feel the same way, and your strength will increase rapidly. At the same time, you can do some arm training with dumbbells at home, such as dumbbell bending exercises of biceps brachii.
