You are a thin man, and your stomach is not very attractive, so you should start nourishing your stomach, get up early and drink a cup of warm water before going to bed. Reduce spicy, greasy and indigestible things in the usual diet structure.

So how do you become a muscular man? First of all, this transformation is completely achievable. Thin people's muscle mass is definitely insufficient, so you need to break your existing muscle balance and destroy muscle fibers through fitness exercise, and then repair and replenish them through protein supplement, so as to increase muscle mass. The theory is that simple. The next thing you need to do is to plan your exercise time and start acting.
