This 45-minute treadmill workout alternates between intervals of higher intensity speed walking at an incline and lower intensity recovery periods. The workout begins with a 5-minute warm up and ends with a 5-minute cool down, with intensity levels between 4-5. In between, it does 2-minute intervals of speed walking at an incline and intensity of 7-10, alternating with 1-minute recovery periods of lower intensity and incline. This interval structure is repeated throughout the workout to provide bursts of higher intensity that burn more calories and help see results according to the trainer.
