A friend of yours on Fitbit or Apple watch that you are in accountability with has a dramatically low step count on a particular week or ongoing basis. 10,000 steps a day should be a pretty good barometer for most healthy active human beings. If that number drops to 50% or less your "friend contract" requires an announcement of a low steps violation.
