Using a snowblower can be cardio…when they are old and hard to start, and more time is spent cranking on it, than using it (that was a “free” one that my cousin “gave” me). Or, when they are brand new, and move snow as fast as the operator can push it, and there is no slipping when I am wearing yak trax on my boots. I cleaned my drive, and 2 neighbors drives yesterday, and worked up a good sweat!
