Has anyone tried to find their actual maximum heart rate, using a stress test like this?
Do target heart rate zones (aerobic, anaerobic, etc.) really achieve the things they say they do (like fat burning or endurance building etc)? Is that really how the physiology works for absolutely everyone?
If I knew my actual max. HR then I could maybe manage my runs for specific targets, though not sure I'm bothered. Just curious (scientific like).
