Q: Mike, I'm trying out your 'no equipment' program, and there is no way I can do the pull-ups. I don't have the equipment needed and I can't buy it, and I've looked everywhere I can think of to find a makeshift one but there's nothing of that sort at all. (And since winter's coming I can't use any branches or anything.) What do I do?

A: Pullups are really a great exercise and you'd be missing out not doing it. All you need is a pullup bar like this. It should cost under $20 and installs in about 10 minutes (screws in any average doorframe -- its length is adjustable). If you absolutely cannot get it you'll need to either get dumbbells to do bent-over rows or skip back exercises altogether, which is of course undesirable. So try to get the pullup bar.
