The Couch to 5K fixates on intervals. You walk a bit, you jog a bit, you walk a bit more—and repeat. Sounds too simple to burn fat, right? (Spoiler: it’s not.)
Those short bursts of jogging spike your heart rate, then the walking brings it down. This “confuses” your metabolism into burning more calories long after you’ve collapsed on the sofa. Science calls it EPOC (Excess Post-Exercise Oxygen Consumption); I call it “the lazy person’s calorie bonfire.”
And the best part? You don’t need to sweat for an hour. The whole workout takes about 20–25 minutes. (Yes, including the warm-up, which is basically walking to the mailbox.)
