At 16 I was 6'5" and about 180. I ate 10,000 calories /day! When I got into lifting for real in my late 20's I still had to eat 8k to hold weight and 10-12 to gain! These days I gain on 4k (I'm 43). Careful what you wish for!
Thanks guys for all of your input. Yeah I have along way to go and i plan to get there with a lot of hardwork and dedication.
I really don't think my bodyfat is 20% though. I'm not that fat lol. When i wake up in the morning i can see a 4 pack when i flex, but that's about it.
you look like a teenage kid who has never worked out. start lifting hard , reading on techniques, different exercises. increase you calories. probably nothing you dont already know.
