Have been reading that using a heart rate monitor is a better way of training and understanding your body and how well you are doing blah blah blah. I have two heart rate monitors one which came with my Garmin and one which came with my treadmill and I have only used them a couple of times. Tonight I decided I would try to determine my MHR which you can do by using a certain formula but they say it is best to physically measure it. If I do the formula I come out at 182 BPM, I have just exhausted myself on the treadmill and done two full out runs and my Garmin results give me a result of 202 BPM (and the other was 200 BPM so almost identical). From what I have read your BPM decreases approximately 1 BPM per year due to the ageing process.
Does this mean my ticker is in good nick or am I just confused?
