Q: in the no equipment workout guide it says pullups...how would you do pullups without equipment?

A: You got me :) Yes, you do need a chinup bar or at least an outdoor siwng set or a sturdy tree branch to do pullups. A basic chinup bar that fits in a doorway can usually be found for as low as $15 in any sporting goods store (and there're many fancier and more expensive variations, of course). If you have no other equipment at all, a chinup bar is one of the best values for the money.
