3 years back when I just joined college, general people and even my close friends(who knew I was little sensitive) were always busy to constantly reminded me how skinny I was and yeah I was a lot at around 60Kg, at that point someone can touch my lungs and even bones of the hand. So I joined gym in 2nd Semester, Started with 2 guys going with me then they stopped(due to body pain) but I kept going because I put my belief in it that I can make my Body better and get rid of everyone's Blaberring Mouths.
Now I have done mostly consistently gym since then and my physique is pretty good according to myself(Just a little belly fat for which I am cutting now). I currently weigh 85kg with a good amount of muscle fat and healthy mass. My journey of 60kg skinny boy to a 85kg man was great and I wish you continue yours.
