On Thursday Stew maintained an average of 1287 watts for 30 seconds on the AirDyne. This was the last of 20 30-second intervals with 90 seconds of rest between each. Relevant to today's post, was he training peak output at that point or did accumulated fatigue prevent him from reaching a true max effort? Of course, 30 seconds is too long to train true sprint capability so it's moot. Yes, it was hard, and totally ruined him but was it sprint training, which - to clarify - was NOT the session objective? Then, on Friday, Maximus did an awful one-hour session combining Goblet Squats with 20-calorie AirDyne intervals. On his last (30th) interval he blew out 20 calories in 10 seconds and hit a peak power of 2155 watts. Terrible. Horrible. Magnificent. Amazing. But was it anywhere near the maximum output he might express when fresh?
