Hi Scott
Are you able to expand on your caveat about the ventilation markers above?
I’ve just started implementing your recommendations from TFTNA and in my initial workouts I’ve found that if I stick to a comfortable nose breathing pace my average heart rate is around 160 bpm. I’ve not done a max HR test but 220 – age would give a MHR of 195 for me. That puts these workouts at about 80%+ of MHR which doesn’t fit with the information on zones you provide in the book. I’m new to endurance training but don’t have a background of doing lots of HIIT workouts either. Is it likely that the ventilation markers you recommend won’t work well for me either? What would you recommend for cases where nose breathing is not an appropriate indicator of AeT? Fallback to traditional HR zones?
I’ve really enjoyed your writing on training. Thanks for sharing!
Cheers,
Chris
