I don't have a goal, I just like to do moderate physical exercise because it feels good and I just can't stay sitting and immobile for days. I go swimming once a week, and twice a week during the winter. I swim for one hour and how fast that goes depends on my energy level that day. After swimming, I might do some painfully slow abdominal and back muscle sets after swimming, just for fun. Or not. Then I walk a few kilometers every day: I walk the dog, I walk to the public transit, and then again from there to work, and I walk or cycle to do local errands. I walk stairs and almost never use the lift. I don't need to look fit but I kind of like knowing I'm fit at least to an extent. I don't want to start panting after taking up a flight of stairs or when I walk or cycle.
