That's a really good point. Obviously with your mention of weight training, you and I are at different levels of fitness, but that is probably not relevant. I split my wood throughout the cold season, when I'm not hiking, canoeing, etc. So my (admittedly not rigorous) physical exertion does span all seasons. My point was more to say that in my own experience, taking care of the wood (something I've come to enjoy) seems to be as invigorating per session as shoveling the driveway at my former home. Another point I was thinking about was that household chores can vary quite a bit from household to household.
That said, I do own and use a snowblower. As un-Mustachian as it may be, I love machines, and have owned ride on mowers when I really didn't need them, etc. Initially, upon moving into my current home in October (first time in my life I've burned wood for heat), I bought the maul to hold me over until I could afford a splitter. Of course now I see splitting logs as "badass" and free exercise.
