Re pullups-
My run got better but my pullups went down, markedly. Part of it was that the pullups I was doing in training, and my OSO was letting me get away w/, weren't sat at OCS. Nothing worse than hearing "one, two, two, two, three, four, four, four..." I thought maybe I was getting jacked w/ a bit, but the same thing was happening to others in the platoon. I think my real problem was that I just can't knock out a lot of pullups. 10s not a problem, but I've never, ever gotten 20 (16 is my max). I've read that tall and skinny body types (like mine) have a tougher time w/ pullups than other body types, but I don't know if I believe it (my cousin's 6'4 200lb and can knock out 30+). I do know that I struggle w/ them, and always have. I do UBDs in the gym- bench, curl, military press, push-ups- and can handle some weight, but pullups are still tough. I can run, so that saves me PFT-wise, but the pullups thing sucks. OCS PT, and the PFT in general, is designed to rate overall physical fitness, and I think it more or less does a good job w/ that. Some people can run, some people can do pullups, and everybody ought to be able to do crunches, so it evens out. The emphasis on running at OCS isn't for PT alone. Its for testing endurance. All the pullups in the world won't knock you out like 5-6 miles a day, everyday, will. Just my thoughts.
