8:00 A.M. for most subjects who have work or classes beginning at 9:00 A.M., and if peak power output and pain tolerance is between 4:00 and 6:00 P.M. in their studies, this corresponds to 8–10 hours after waking. I am a night owl, and my average wake time is 11:00 A.M. Using this average,16 8–10 hours after waking would put my ideal window between 7:00 and 9:00 P.M.
