I've read a lot of heart rate articles and by most calculations, running to build an aerobic base (say 70% of MHR or of WorkingHR + RestingHR) should have me running at about 156 bpm.
My problem is that I'm walking to get this heart rate. When I run at a comfortable pace, in fact one that feels very slow indeed, that's when I reach this heart rate. Running at a comfortable (faster) pace than this for 40 mins, gives me a heart rate of 170 bpm!
Yet I feel as though I'm in a lower zone because I can hold a conversation and I'm not going terribly fast. (p.s. I've had blood tests recently and everthing is fine).
One professional runner at my gym has suggested I simply ignore the heart rate monitor. The physio at my gym says I should obey the heart rate monitor, no matter what. Who is right? What should I do? (I am 33 yrs old, female, and have been running 3 times a week for the past two months).
