I think it's fair to point out that the biggest barrier to his running performance will be his weight, even absent that his actual health long term too. I didn't get through the video but find it commendable that Aubrey made some content about considering your weight for racing when people pitching to the beginner runner crowd shy away from it - for obvious reasons. Like fine running might not be your be all end all and it's a tough subject but I think it pays to be realistic about these things.
Agree that Anya really shows her worth as a 'professional coach' in the video. Just no constructive or useful input, actively unhelpful at times. Explain the purpose of the workout, what paces it's at and why - how you might modify the workout for whatever reason and stand there with your big jacket and stopwatch calling lap times like any other self respecting coach would do.
All in all workouts like this fuel a real low stakes conspiracy I believe - apps like Runna create these workouts not focusing on performance benefits or athletic development, but for Strava graphs and instagram shareability. Happy to be corrected but I just don't see either of the workouts as being good for these runners. No pace discipline and specific work being undone by the 'just bury yourself' attitude, imo the breaks are too long when they aren't stressing their systems that much. The limiting factor isn't that they're going top end of vo2 work, or needing to stop themselves going too much over their lactate turnpoints, or even speed/power production - it's just that they're carrying some extra timber and lack general fitness.
But that's boring for a coaching app to be preaching, and you can't post a sexy split graph on an instragram story if the coach says mate we just need to get you losing weight sensibly and getting up your general aerobic fitness so it's mostly easy running with a bit of steady/tempo work when it's appropriate before we think about harder workouts.
