I am 16, 5feet 8inches tall and I weigh about 50kgs,which is less than what it should be. I am quite skinny. Despite being skinny I am quite fit and have no health problems. My only problem is that I have no flesh on my body especially my arms(they can easily be confused with iron rods).
I am looking for advice on building my body structure and gaining fat as well as weight. I also want to build some biceps.
Help me, I am sick and tired of being constantly referred to as thin or skinny.
