If we're going to dismissively summarize, shall we at least summarize it correctly? > The SIT protocol consisted of 3x20-second ‘all-out’ cycling efforts against 0.05kg/kg body mass, separated by 2 minutes of low-intensity cycling (50W). You're right, that's not one minute. That's 20 seconds high intensity spinning spaced out with 2 minute "just regular biking" sets. Turning that into "it's 8 minutes, not one minute" takes some doing. Anyone with a home exercise bike can comfortably repeat this regime.
