I have tested umpteen heart rate monitors (HRM) over the past few years for RW and, while I love their accuracy, I don’t always love how they feel. I am someone with significant rib flare from making whole humans inside of my body, and things rub weird. That’s why I was so intrigued with Coros’ arm band HRM .
