Uh..no. I'm not sure you dare clear on the chart. Max is the max - the top of zone five on the chart. I think you are refering to AT or anaerobic threshold...the point where you stop burning equal amounts of fat and sugar and burn more sugar and produce more lactic acid and the top of zone three/bottom of zone four.

There is a point where you are unable to get your heart rate higher. That is max and I physically cannot exceed that. For me that happens to be around 175-180 bpm. (I train to increase that max.) 85% of that is 153, which usually works out to be my AT. I can stay at 150 for well over an hour. If I used 65% I would be at 117 bpm, a warm up rate.

The problem with the 60-65% most people understand is that there is no way to acurately determine what that actually is. They base the old method syrictly on yor age. That doesn't work because your age has nothing to do with your fitness level. Any of the methods short of a stress-type test doesn't acount for fitnes levels and can be off by as much as 30 bpm. I'm a good example and am about 25 bpm higher than most age charts would indicate. I'm confident because I've been tested.

There is a real science to this stuff. That's why athletes today can do so much more. Training is more than muscle and skills...the science is training your body to move more blood efficiently which carries more oxygen.
