Four shorter sets of 40/20 intervals at 120% FTP. The same intermittent VO2 stimulus as the 3×10 version, broken into four digestible sets.
Repeat 4 times
Repeat 8 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, HIIT.
