For those trying to do pullups follow convict conditioning or the primal blueprint exercise guide for a progression guide (I am sure there are others).
Try Paval's "greasing the grove". What ever stage you are for 5-8 reps try doing one every time you pass a station. So if you are on the inverted rows (Australian pullups) stage and are managing 10 reps every time you pass the station do one rep....it will get you to your goals.
As someone who can do chins comfortably my goal for 2012 is the one arm chin up....does that count for this thread?
Eating primal is not a diet, it is a way of life.
Don't forget to play!
