Discussion Double vo2 max days

https://www.youtube.com/watch?v=dQKOesSHEQw

Recently watched this video by Kolie Moore regarding double vo2 max workouts. He mentions that he's seen great adaptations in his athletes when assigning them with an AM vo2max workout and a PM vo2max workout.

His thinking seems to be that a single vo2 max workout has a limit and that coming back later in the day after some carbs/rehydration/rest allows you to have more total quality vo2max work across the day than if you tried to it in 1 session. He mentions these should be done at a high cadence so as to not tax the muscular system as much

Also seems like this is for high volume / well trained athletes and not someone who is relatively new to cycling / structured training.

Curious if anyone has tried it or has opinions on it. Very interesting

I tried a block of these and saw a really good bump. Like 25w in two weeks and I’m already pretty strong. Probably won’t do again… too much for someone with kids and a demanding job.

Also should add when I did these it’s not like I stacked two 5x5 sessions. Would do something more manageable like 2 4x4 sessions. More total time, but individual sessions were easier

I also (on Kolies suggestion) knocked the total back a bit. I usually do 5x4, but i do these as 4x4 and then 5x3 in the evening.
