So it turns out, according to Garmin, that my fitness age is 74. My fitness is poor and I’m in the bottom 5 percent for my age bracket.
Colour me shocked.
I thought it was because of inactivity due to knee replacement surgery. Garmin doesn’t track my weightlifting or my physio so all it knows are my steps per day, heart rate, rest, and numbers of kilometers ridden. And yes, it’s true I’m just riding 50 km a week on the trainer right now. That’s down from my usual 100 or 150. My step goal is in the 5000-6000 range and I meet it most days but that’s down since I had knees that worked.
Still it seemed wrong. I wouldn’t think that someone who rode their bike 50 km each week and walked more than 5000 steps each day would be in the bottom 5%. My resting heart rate is in the low 60s and that’s pretty good too.
It’s true I’m not my usual fitness self but bottom 5%?
So I googled how Garmin calculates fitness age and I remembered one more piece of information Garmin has, my weight.
Argh. Argh. I should have guessed. I should remembered Nicole’s blog post about this. And in her case there was only a two year gap. The gap between my actual and Garmin’s fitness age for me is 16 years.
Bundling weight into the definition of fitness doesn’t even make sense to me. You can no longer ask about the relationship between fatness and fitness because on this way of measuring fitness, the weigh scale is built in.
I was embarrassed at first to blog about this. I shut off the Garmin app and stormed around the house a bit. I did some chores in a loud grumpy fashion. But the more I thought about it the more I realized it’s their problem, not mine. I’m going to write and ask them about. I’ll let you know if I hear anything back.
