Some sources suggest that you are not maximally using your fat burning energy pathways at higher energy intensities. Like this study, a clip of which is shown below:

This kind of suggests that the top of Z2 is where you begin to sub-optimally engage your Z2 / fat oxidation energy pathway.
No, you don’t have to exercise at your maximum fat burning zone to improve your fat oxidation capacity. Fat burning
capacity is about the mitochondria.
To improve fat oxidation capacity, build more mitochondria, and improve their function. Build more mitochondria by riding more hours. Improve mitochondria function by riding hard.
