Yesterday, that recorded over 12000 paces when my only means of locomotion was a 4 mile round trip by bicycle to my dear friend’s house. I don’t think that, and the rest of my daily activity, will have notched up more than 5000 paces or equivalent. What did the job was making a cake for my Dear Wife’s birthday. Beating the ingredients together in a none-too-warm kitchen not only counts as paces, but it was sufficiently cardiovascular to have registered 92 “zone minutes”, ie of a slightly elevated heart rate.
My partner has a Fitbit, and it does similar: kneading dough seems to be a good way to get "steps" in, and he routinely registers many more "active" minutes, or whatever they're called, than I do, despite not being more active.
I have a Garmin watch, and it's much more "mean" (I think it's more accurate). It takes quite a bit to convince it I'm being active (walking pretty much never registers, unless I'm climbing a mountain or something). It also has less of the congratulatory nonsense.
Does it track if, say, you do a turbo trainer session? Are there other options to consider?
Most can do, to a greater or lesser extent. I only use mine to measure HR, so I can set it to "indoor bike" and it will record that I've done it and show HR over the course of a session; if I were using speed/cadence sensors, it would track that too. Fancier versions can also sync to power meters.
I guess you could wear a normal watch on one wrist and a smart watch on the other, if you wanted to. Two watches on one wrist might be a bit odd.
