I’m working with a friend of mine — Mike Bowyer — on a designed, intentional, training program. One of the critical components is working for specific times in very particular heart rate zones. So I’ve bitten the bullet, and am trying a FitBit. Online commentary seems to be that it’s not super-accurate, but I’m hoping it will do at least an ‘ok’ job of thoroughly recording heart rate during — saw this coming didn’t you? — parkour activities.

…until I smash it on a brick.
