I've never actually seen Angel, and only a couple of episodes of Buffy (nothing against them, they're on my To Do list, I just don't watch a lot of TV). From what I have seen, I'd probably better see them sitting down first so I can figure out what's going on.

Depending on how smart the excercise machine's computer is, it might actually take into account which gear you'd typically be in if you've got n amount of resistance.

Seems to be the same at all resistance settings; it's a pretty basic model. I guess resistance just translates to 'uphill'.
