> I don't think I agree with that definition of exercise. I don't see a compelling reason to dispense with a dictionary definition > There is not a requirement that it must be for the sake of developing fitness. It's not an exhaustive definition, but it is practical one, it's also unambiguous in its meaning, and applies to discussions about medical outcomes. Escaping from a wild animal is technically exercise but it's not really what the word is meant to convey. If you spent a day in the woods escaping from a wild bear, when you arrived home and someone asked you "what did you do today", you wouldn't say "I was out exercising" because that's just not how the word is used. > Well, no, that's not quite true. Yes it is true. We could make predictions about weight and muscle mass over time.
