This doubt many and many of you have to ask it over and over again, the answer will be given as briefly as possible and in a way that you can understand.
It turns out that your genetics type is predominantly ectomorphic. There are 3 types of genetics at the human level, which can be 100% pure from just one of these or a mixture of both, always being one that predominates.
In the case of the answer that I am giving you, the type of genetics that predominates in you that you are reading this paragraph is ECTOMORPH. This type of genetics requires that for you to have an increase according to your desire, you must consume a fairly high amount of food intake, and for this you have to do some calculations between these first in addition to the respective anthropometric measurements A GENETIC TEST, and not precisely It is necessary to go to great specialists in genetics, so do not panic.
I have seen how in many training centers people make the serious mistake of leaving carbohydrates believing that this way they will increase and it is totally false. If you do not do the respective calculations and consume the necessary amounts and the necessary food and train as your genetics demand and rest enough, be sure that you will not reach the goal, many look for the easy way through steroids, but the reality is that these either They lead an easy path and they need a lot of work so that you can obtain the desired effects and not complicate your health.
Anyway, I wanted to write this article so that you have a very small notion of why you ask yourself that question and only seek to get money from you but you do not achieve results.
