So my wife works full time, and on weekends, we do errands bullshit together and do not have much time for anything beyond that and time with friends.

She wants to do something to build up her butt, squats and such I guess, but her rather ludicrous qualifier is,

"it can't make me too sweaty."

She has a lot of very long curly hair, and apparently, having to wash it all the time is not possible or otherwise undesireable. So she wants to do something that we can do while she is watching TV that will not make her have to wash her hair, but will pop those cheeks up a bit.

Anybody got some advice?
