Yarn winding = steps?

[HBF]

This morning I went for a short walk, and after that I had about 3500 steps, which is what I would expect.  Then I sat down and wound some yarn from a cone into balls, and shortly after that I was surprised to feel my Surge buzz, and say I had reached 10,000 steps!  Later I wound some more yarn, bringing my daily step total over 20,000 steps -- what is going on here?

Wrist models will do that as it sees your arms moving. When doing this I would remove the unit until your done yarn Winding
