Had a great #legday! I finally (after like a year) changed the battery in my #polarwatch #heartratemonitor and compared it to my #fitbithr during this #workout… So disappointing! They weren't even in the same ballpark. I always knew my FB wouldn't be super accurate but it was like it wasn't even trying 🏻 Might change to a less bulky one now that I know the heart rate function is basically useless
