E! News — the five-minute Revenge Body workout, with Zuri Hall

E! News correspondent Zuri Hall — now a familiar face on Access Hollywood and NBC's Olympic coverage — did not want to interview me from a couch. She wanted to do the workout. So we took it outside, no gym, no equipment, no excuses, and shot the entire five-minute routine in real time while the cameras rolled.

The routine came out of my work on Khloé Kardashian's Revenge Body, where I coached a client through a fifty-pound transformation using the same principle: short, dense, body-weight movement done consistently beats long workouts done occasionally. Five minutes is not a compromise. Five minutes is the amount of time a busy person will actually protect, day after day, which is the only variable that has ever predicted results.

Watch Zuri go through it and notice how quickly the intensity rises. If you are in midlife and the idea of an hour at a gym is what is stopping you, start here instead. Five minutes tomorrow morning, before anything else, and let momentum do the rest.
