Long slow endurance for mitochondria building

I got scoffed at, mocked, and harrumphed for my “references” about the time required for these changes.

For context:

75min Z2 enough?

I have been doing low volume plans and adding 2-3 75 minute Z2 rides on the “off” days. I this enough volume to make a difference? I don’t want to be on the trainer for longer.
