Long slow endurance for mitochondria building

I thought it was 3+ hours. I’m going to change my plan to just 15 mins 2-3 times a week instead of having a nice long ride on weekend.

You’ll only need to devote 12 minutes, but you’ll have to go a lot harder than zone 2.

75min Z2 enough?

I can name that song (increase mitochondrial biogenesis) in 12 minutes. [Screenshot_20210307-115131]
