Workout Update: P90X3 and PIYO doubles workout- Day 14

Day 14 was a rest day in X3, and the core workout in PIYO.

Core is a mix of easy (or at least easier) core-focused exercises and some hard (to very hard, depending on whether you modify) exercises. What is nice is that it has a mix of standing, lying down, and seated exercises, and like the other workouts, you are moving the entire time. So, you burn a lot more calories than just doing crunches and leg lifts.
