HR Zone Advice

by Swami Dave   November 20, 2012  


Having a bit of difficulty establishing 'correct' heart rate zones on a Garmin Edge 500 (5 zones available). As is usual with the internets, there is a wealth of conflicting advice out there. Garmin suggest zone 1 starting as low as 50% of MaxHR which seems to contradict the majority of sources that place the start of zone 1 at around 60%. Garmin's own manual cites the five zones as being 50, 60, 70, 80 & 90% of MaxHR, which seems oversimplified.

Anyone have any advice on percentage values? Thanks!

Just checked Garmin's site again and it quotes its zones as %HRR values (using Karvonen) not MaxHR, which makes a bit more sense. I may not have read the manual properly.

I also use her karvonen method as I have a low resting heart rate.

This gives a percentage using working range max-min,

Just use as a very rough guide and see how it feels?

Yep, karvonen or slight variations of it which take into account your resting heart rate. Basically it's 220 - your age. your maximum hr is 80% of that figure. Have a look at (you don't have to subscribe). A normal interval session for me takes me slightly over my max hr
but less than 5%.
