Morning ladies! Hope you all had wonderful holidays!
I have a question about heart rate levels. I'd always gone by the old adage that to figure out your target heart rate you subtract your age from 220. FI got me a pretty nice Polar HRM as a Christmas gift and this morning I was playing around with it on my run. I was checking my average HR at the various speeds I tend to run at when training and seeing how "efficient" my runs are. Going by the 220-age math my runs are keeping me in a lower HR range. However, my HRM has my high THR around 167, significantly lower than 220-age. I'm pretty sure my HRM is more accurate than my old adage and that it's probably pretty spot on with everything, but I was curious about your knowledge on the subject.
Either way, I had a great run this morning; a 5k in under 30 minutes, which is pretty decent for me, especially not having worked out in a few days and eating pretty poorly. So I'll take it.
