40/20 efforts are completed at a power just below your Maximal Aerobic Power (MAP). By splitting the effort into 40 seconds of work, with 20 seconds of recovery, you can accumulate more time at this intensity than you would if doing it as a continuous effort. This is a development of the previous week's 30/30 session - a higher workload this week!
