I've read many posts about Fitness Points / Fitness Age / VO2Max and they state that you have to either run or cycle at a certain heart rate to lower your Fitness Age. Every week I'm told I'm "Imroving" my Fitness Age, yet nothing changes. According to my statistics, I'm consistently working out in my peak heart rate range.
Perhaps I need to phone in my workouts, climb to a Fitness Age of 102 and then work out normally and watch my Fitness Age drop. :-)
I know this is just a motivational tool, but for a watch that I love (this is my 2nd TomTom) this feature utterly fails.
