Is this measured with a Polar ? I know 50 year olds that report 240 BPM during cardio with this so i wouldnt trust it…
The test was taken when I was approx 175lbs… I am 220 now (probably less) and jump\run much higher\faster…
No - this is me counting through 15 seconds. It’s pretty hard at first, but you get better with practice at counting a heart rate that high.
