one of these days i want to get in the p90x exercises (when i actually have 3 months to commit to it). i was just wondering, though, from those of you who have done it/are doing it: where do you actually do the exercises? i know it's on dvds and you have to buy a bunch of equipment for it and whatnot, but it seems like a lot of the exercises are inconvenient to do in a living room, or in a house in general. how you go about doing these then? thanks.
