The pursuit of lactate clearance, a path shrouded in mystery. The optimal duration and intensity of hard intervals remain a subject of intrigue. Research whispers that a 2:1 work-to-rest ratio may not be the most effective approach. Perhaps it's time to question the doctrine of high-intensity intervals and uncover the secrets of moderate-intensity efforts. The role of active rest, once a footnote, now demands attention. Aggressive active recovery strategies, like high-cadence spinning, may hold the key to accelerating lactate clearance. But what lies beneath the surface? The truth, much like lactate itself, remains elusive.
