HRM v MP3 Player
I have been running with a polar s610 HRM and a sony mp3 / cd player went out the other day with no chest strap on and my watch still shown my heart rate and Kcals burnt??? Anybody else had the same problem?
Did it keep pace with the tempo of the music?
thinking about it, it could have because the heart rate varied dependant on what track i had on.
