My Fitbit auto logged exercise for me today.
I thought this was weird since I've pretty much been sitting in meetings all day, so I went into the log and at the time it is logged, I'm not sure if I was in the shower or straightening my hair, a process of blow drying with round brushes and flat ironing, but it decided I swam 219 yards.
I'm impressed with my bad-ass virtually swimming self considering I can't swim.
