I thought I read something about this somewhere, but I can't find it now ...
I've been reading all the info on MAF that you all post, and I got the book and have started reading it. I get the idea, and have been trying to keep my heart rate in a certain range, but for the first time in a while I got more strict with it today. I am still finding it very difficult to keep it in range. By age (37) I should keep my heart rate about 143, so I've been aiming for 140-150. To do that, I am going REALLY slow, so slow I'm not going to admit to it. I have to do a LOT of run-walk-run, and when I download my Garmin my heart rate graph looks very much like a saw blade instead of any kind of wave form.
Is this normal? Do I just keep at it? I gave up a while back on trying to keep my heart rate that low because I didn't feel like I was actually doing enough running, so maybe that's my problem?
