>How did you learn to do Chin Ups?
I never allowed myself to become a weak fatass
I was always able to do pullups.
Find a tree or something and study under it.
Every 20 minutes or so do 5 pullups, not one after the other, but do at least 5 before you stop.
Keep going until you can do 10, then go to the gym and hold 10lb in your legs and go up in weight.
Get lats.
