I do my aerobic exercise on an elliptical machine in the winter and there's a small drop off in the number of hours I put into it as compared to my 8-9 months of riding, but I can definitely say that the elliptical is a very intense workout comparatively by virtue of being a whole body workout. In the meantime, I do as much or more walking in the winter (probably more as I'm more likely to walk a short hop than bike it as I would do if the weather was warm and the street not sloppy). And what the hell is the taking the stairs vs. taking the elevator bit about? Where do you encounter a lot of outdoor stairs and elevators?
Am I supposed to rent a dog? You have no point here whatsoever except to make an obviously false claim about indoor machines.
Do you have trouble understanding examples. Or rather do you have trouble understanding the concept of what an example is? Walking the dog, taking the stairs etc. were just that.
Also I though (falsely apparently) that you understood what the whole point of this discussion was. It's not the exercising in the cold that's the supposed issue. It's the cold itself. If you go outside when it's (actually) cold, ie. near or below freezing your systolic blood pressure can spike 20 mm hg just by stepping out the door. If you get cold your blood pressure can further increase and then you can start getting those aforementioned clotting issues. Just by being outside you breathe the cold dry air. There are other effects as well, but those are a bit on the nitpicky side
When properly dressed and exercising outside you'll unlikely to be cold. Probably the opposite in fact. Exercise raises blood pressure for the duration of said exercise but the effect is slightly different as it also trains the vascular system. You'll still be breathing the cold dry air and doing it more frequently. However it takes a lot lower temps than freezing and quite high intensities for long durations to damage the lungs in the cold (it is possible though).
But if you're an old out of shape male and going out doing zone 4 or 5 work (shovelling snow like you have something to prove) you're potentially gonna have a bad time.
