Blogilates founder Cassey Ho incorporated the core-strengthening elements of her POP Pilates method with high-intensity interval training to create PIIT28 (which stands for Pilates Intense Interval Training). There are six workouts per week, and in each 28-minute (and 40 seconds) workout, you'll go through seven different exercises for 45 seconds each, resting for 15 seconds in between. Then you repeat that set three times. As for the exercises themselves, they switch off between cardio exercises and Pilates moves.
