My understanding is that the main point of VO2 max workouts is to spend a lot of time at a high percentage of maxHR (specifically, I’ve seen 90%+ discussed a few times). Given that, I don’t understand the point of VO2 max workouts that have very long rest intervals like Baird-1 https://www.trainerroad.com/cycling/workouts/139277
The rests are long enough that I don’t come close to 90% of maxHR at all, let alone for any significant duration. Baird-1 is included in a lot of triathlon base plans, so I assume it’s valuable, I just don’t understand the goal. Is it just included in Base plans as an intro to intervals in this power range? Prep work so that actual VO2 max workouts are less of a shock when we start a Build phase?
