OK I Have a question regarding the categorization of these 2 workouts.
All watts based on my FTP!
Ainsle +4 is said to be Threshold wo.
Tionail is said to be Vo2 max wo.
Ainsle +4 has 6x4min at 301W with 4 min recovery in between.
Tionail has 3x4minat 298W with 4 min recovery in between.
How can Ainsle +4 be a threshold WO with lower wattage and less repetition?
Shouldn’t in be the other way around?
Or am I missing something?
