This has always been something I have been interested in from around a year after starting running , especially when I was running regular 10k's
Like many, I found it very frustrating as I needed to stop running and walk for a while every few minutes to keep my heart rate below my MAF Max.
At the time I didn't quite grasp the fact that the method doesn't care if you are running or walking , just that the time training is at or below (ideally below) your MAF Max.
At the time I was using the MAF formula of 180 - Age with no other tweeks.
Following my heart attack in February I have obviously become even more interested in the function of my heart !
Having re run C25k since then and having lost 2.5 stone, coming off Beta blockers and controling my glucose levels my HR is a lot more stable and this seems like the perfect time to give this more serious attention.
I will of course need to tweak the formula further (as explained in the video and on the MAF website) following the heart attack.
But what better way of regaining my fitness.
I use a Polar hr chest strap on my runs as I find it has more stability than my Garmin .
I used them many years ago when I gave up smoking (26 years ago) and have now bought a newer polar strap.
So from now on the only metrics I will be watching are HR and time !
I know quite a few here have used and are currently using this method to great effect!
