Subject: RE: Heart rate monitors A basic heart-rate monitor properly used is most likely the useful tool available for endurance athletes.
A heart-rate monitor will teach your body to burn fat for fuel as opposed to glycogen when you train in your fat-burning (aerobic )zone.
For example, the average marathoner has about enough glycogen stores to make it to about mile 20 or so in the marathon if they are running with an elevated heart-rate or in their (anaerobic )zone.
At that point they hit the invisible "wall" and their marathon becomes a death march.
However our bodies have enough fat stores to run three marathons or more.
The problem is that very few people realize this and so keep hitting the wall over and over again in marathons and half-ironman and ironman distance triathlons.
So is there more to a heart-rate monitor than just a way of telling you what your heart-rate is? You bet there is.
Find yourself a book by Doctor Phil Mafetone on heart-rate monitor training and you will learn a lot and become a more successful endurance athlete.
