Day 2 of Week 2 starts with an 8-minute HIIT cardio section, followed by a 10-minute strength section, the next section is both strength and cardio (one-legged squats and 100 high knees) x3 rounds, then back to the beginning for another 8-minute cardio section, followed by 10-minutes of strength. You'll feel really good after completing this workout. You'll need a chair, a heavy kettlebell or dumbbell (she uses 20lbs), and then a set of light/medium dumbbells (she uses 8lbs).
