At this time of year I don't do a great deal of what I class as exercise.
I work outdoors, so I walk around 11.5 to 12 miles a day anyway - and often come home freezing cold and soaking wet - that I don't count as exercise unless I run my commute to walk, as it doesn't raise my heart rate significantly because I've been doing it too long (my body's used to it).
I don't get up and go out early, as I'd have to dry off and defrost before starting work.
I'm too tired after work, and I'm not going out to get wet again after I've dried off and defrosted on reaching home.
It's also the busiest time of year for work, so I don't have a lot of spare time anyway!
But on days off work I regularly volunteer as a dog walker with a kennels that rehomes ex-racing greyhounds. On a Sunday we sign up on a rota for the following Monday to Sunday, and once signed up they expect us to turn up - so no backing out just because it rains or snows, although they sometimes cancel the walks as the weather isn't good for the dogs (we had a number cancelled over the summer because it was too hot for them).
And I very rarely drive or catch buses to go and do shopping, so that's all mileage walked too. Not uncommon for me to do a 7-12 mile round trip for groceries at least once every 6 weeks. Or 13 miles into the city centre to do some Christmas shopping or attend an opticians appointment, although I do get the bus home those days.
