I'm 56 and I started using my Vivosmart 3 at the beginning of July, so only about 3 weeks ago.
The first time it gave me a Vo2max reading, it said I had a fitness age of a 60 year old. Fair enough, I thought, that's why I've got it, to motivate me to exercise and give me some positive feedback about my progress.
So I started to walk a lot more. Even the occasional jog. Eventually the hard work paid off and I was rewarded with a Vo2max reading that said I had the fitness age of a 57 year old.
Spurred on by this I continued to exercise.
I was looking forward to the next reading. I'd check it every day, looking for the moment when my fitness age fell below my real age. Finally after miles of walking, the third reading came.
67.
So my question is, is my Garmin trying to tell me that I'm at death's door and that exercise is futile?
