the bigger the disturbance from homeostasis, the greater the adaptation. So going from homeostasis at rest to a light jog is good. But going from rest to a full run is better. And best of all is going from rest to an all-out sprint. And even better than all that, if you’re really looking to cram the biggest performance benefits into the smallest amount of time? Repeat the number of disturbances in a single workout by doing intervals—whether they’re light-jogging intervals or as-hard-as-you-can Wingate tests.
