Forums >Health and Nutrition>Is this heart rate strange?
I am using a Garmin 301 and find it very useful. Today I used the HRM for the first time and got this result Starts at 100 then gets to 150 after 5 mins and from that point on is a sloping curve up to 170 at the end. A pretty much a straight line in fact. Now, as I am 55, have resting rate of just below 60 it seems that according to all the formulas I am training way above 70% which is what I should be aiming at. It is true that at the end of 32 minutes I am pretty well worn out. Perhaps the clue is in the heart rate. Anyway, any experience of this please? Thanks
