there are 168 hours in a week. With most people spending 1⁄3 of that asleep (56hrs, 8hrs/night), 20 hours on lesswrong per week, 40hours in an average work week, before we take two hours out of each day to spend exercising (14hours); what are we taking those hours away from? Can you do what you were doing before without the time spent exercising here?
Note that exercising affects your need to sleep, so more minutes spent exercising don’t necessarily translate to fewer minutes available for other stuff on a one-to-one basis.
But there are two contrasting effects here—by exercising, you’ll need to sleep more, but you’ll also get more hours of actual sleep per hour spent in bed trying to sleep—and it’s not obvious which one will dominate. It probably depends on lots of things.

I’m not sure whether that’s true. Dancing well can in my experience mean sometimes mean that I get by with less sleep.
I’m not sure. Meditative trance states do have shown in some cases to be able to replace sleep. When I dance well I think it’s plausible to be in a trance state which cuts down on sleep.

That’s probably the second of the effects I mentioned, if you interpret “actual” narrowly enough.
I’d guess that with different types of exercise, e.g. weight training, the first effect might win instead.

Good point.
