What is the proper way to do an anaerobic workout?

Aerobic because the recovery between intervals is way too short?

I’ve been editing workouts like glacier and wynne and adding more recovery between intervals to make the workouts more anaerobic:

  • at least 10 min after 90 sec/2 min intervals (± 140% ftp)
  • at least 7 minutes after 1 min intervals (± 160% ftp)
  • at least 4 min after 30sec intervals (± 200%ftp)
  • at least 4 to 3 min recovery after 20 and 15 sec intervals (200% ftp or higher)

And the total workout never exceeds 90 minutes (60 minutes most of the time)

Would that be the way to go?
