Three minutes of high intensity training weekly equals hours of traditional fitness
the verdict
SUPPORTED
the evidence backs this
confidence 95/100
Extensive exercise science literature demonstrates that low-volume high-intensity interval training (HIIT) can induce similar cellular, metabolic, and cardiovascular adaptations as hours of traditional endurance training, making it a highly time-efficient alternative.
