I turned 17 on march. Started lifting consistently at 8/20. I was at 66kgs/143lbs(?) Aprox. At the beggining of the year (2020) but I had more fat than what I would like to, I always had a very bad nutrition, I would eat easily 400g of carbs x day, I used to only eat pasta with bacon and all those sauces plent of fat, I am Lucky cuz I always liked to workout a lot and that prevented me to become a fatass. I never noticed clearly my abs till a copule months ago and I am very happy but I can't belive I still weighing the same since my 14s.
My current goal is to hit the 150lbs mark getting the less fat that I can.
Also important, I only am 164cms/5"4.5'.
