How do Cardio “Zones” work?

329 views

I’ve been cycling a lot and I always end up in Zone 3 or 4. People say Zone 2 is the best and the “fat burning” Zone.

Does this mean I’ll lose more fat/weight in the same amount of time exercising if my hear rate is lower than it has been!?

What are you using to determine your zones?
Your zones change as your fitness changes so you really need to be doing a FTP test if you are making progress.
This is where a power meter becomes important.
