A bunch of my friends are always doing workweek challenge or weekend warrior challenges, and I always have a million invites. No big deal, I accept most of them, but I'm always at the bottom of the pile because I'm mostly doing swimming and yoga for exercise these days. The one thing I usually do a pretty good job at is flights of stairs. It seems like you can't do challenges for anything else other than straight steps, right? No stairs, no minutes of activity, etc.?
My brother puts his on my niece's ankle. I wish I was kidding.
My husband's work had a specific rule that you cannot put the fitbit on your dog.
LOL.
I used to work with someone who used to rack up tons of steps by riding his horse. Apparently 4 hooves, double the steps, even with it just on his wrist. Can't independently verify.
