Huh? We’re talking about activity trackers. I’ve mixed thousands of sacks of concrete, but I’ve never wished that my watch had a “mix concrete” activity. Ditto for slinging roofing up a ladder or framing walls. I tend to take my watch off when I swing a hammer since I wore it on my right wrist and it was irritating.

Activity trackers are for tracking activities about which you need metrics in order to get better. If you’re getting up out of the aerobic zone while doing manual labor you should quit smoking, not use a watch.
