i don't have a HRM yet but am researching and looking at the forums for suggestions, i just looked up a heart rate chart and found what they want mine at. there was a chart for resting HR mine is in the ball park of an 18 year old (i'm 54) at 47 bpm resting. i'm doing a stress test tomorrow and i'll see what turns up with that.
so the big questions is do i really need a HRM? or is it a gadget to just get more info i may not need?
