This session is designed to increase your FTP from below, working predominantly on your aerobic metabolism. In time, your body will become more comfortable with these powers, and your FTP will increase. By the end of the final interval, you should be tired and struggling to hold power, but not at your absolute limit...This is my favourite Threshold workout, which can be extended easily and with clear progression.
