Demonstrably untrue, but this is just the same place we got to last year, where the ball was left in your court … > [@SS level 10 what’s next?](https://www.trainerroad.com/forum/t/ss-level-10-what-s-next/94530/25): > > Thanks hub… I think. @Slowwithouttwitch it’s actually not driven by substrate oxidation, it’s about maintenance of energy state.
