Difference Between Peak, Cardio and Fat Burn Heart Rate Zones

[JoyfulStephanie]

I'm not sure I am posting this in the proper category?

When I run, the peak heart rate is the highest with very little cardio and fat burn.  When I bike, the opposite happens and I have very little peak heart rate and much higher cardio and fat burn heart rates.

What does this mean?  What does this indicate about my running and my biking?  

Thank you!

Stephanie, 😊

That fits with my experience, at least back when I used to run and bike.  I think running tends to be more strenuous.  On a bike you can stop pedalling, go down some hills, etc whereas running you have to keep moving your legs - no coasting.  And it's easier to just concentrate on running, as opposed to watching traffic and keeping your balance on a bike.  Of course you can work just as hard on a bike, but it seems to take more mental effort to keep up the intensity.
