Three sets of ten 40-seconds-on / 20-seconds-off intervals at 120% FTP. Intermittent VO2 training that accumulates more time at max oxygen uptake than steady intervals.
Repeat 3 times
Repeat 10 times
VO2-focused intervals raise aerobic ceiling and repeatability for attacks, climbs, and hard surges.
Useful when you want sessions that match tags such as 40/20, VO2 Max, Microbursts, HIIT.
