All right bro, first and foremost, CALM DOWN. Relax, it happens to ALL of us. Do you have a diet already? If so add a little, not very much, of the protein that you are consuming. For example: Breakfast was 3 eggs, now it's 4. Little stuff like that, oh! And very important, try to get the most protein-rich meal at dinner and of course the Greek yogurt before going to sleep. Those will help you gain weight in muscle. Also, HIT THEM WORKOUTS BRO!!!💪🏼 Well, I don't know much, I probably just gave you some part of what you really need, but I hope it was not only true but also helpful. Wait to hear what Christian has to say about it. I wouldn't want to be screwing up!!!
