Zone 2 is boring, and that is why it works

Hard sessions photograph well. Easy aerobic work does not. That is why the internet over-indexes on suffering and under-indexes on the hour you can actually keep.

If your easy days feel dramatic, they are not easy. Heart rate, conversation pace, or a simple nasal-breathing test will tell you faster than a new watch face.

Keep one hard session. Fill the rest with work you would still do after a long desk day. Consistency is the unfashionable stack.
