The dumbbells aren't a problem, but the chin-up bar is. We have only two doors that would hold the bar; one is the door to my 10mo's bedroom (he is usually asleep while I'm exercising) and the other is to my 8yo's bedroom. They're both a bit of a distance from the loungeroom. Aside from that, we're in a rental house, so I don't think they'd be too happy if we started putting holes in doorways. Having seen the DVDs, can you tell me if there is some other exercise alternative for the pull-ups? If not, I might have to look into some type of small, cheap free-standing one.
It would be great to see some photos once you've figured out how to upload them.
