Pretty much I use mine to just get me over my minimum threshold for effort and it's nice to know if I fared better this time , when doing that steep slope. Come down 12 beats, that seems a real feat.
But ok, my resting heart rate is like 75-85, I think is about normal. So I go out for three hours and I see my average Heart rate is like 135-145. What information can be gained from that knowledge? Calories consumed, etc. thanks.
