Hey Donut, when you look at WKO’s Polarized Training dashboard do you have any periods where weekly training at >85% vo2max was above 10%? Just curious given your comments about having to do longer vo2 intervals (I’m the opposite). I’ve got a longish 15 week “build” period in 2017 where >85% vo2max was between 10-29% every week, and I remember it being both hard (always falling asleep after dinner) and volume was inconsistent due to smashing it all the time and knees couldn’t take the punishment. However I pushed FTP to an all-time high AND could do really long 40-80 minutes at +/- threshold AND mostly held fitness until November despite cutting back volume June - September.
