I had a harder time with the Plyo workout this week because my leg muscles were very sore but overall I feel like I got a lot more cardio out of my workouts since my coordination was better.  I love this program so far and next week I'll get to see some of the longer workouts (60 minutes), so I'm excited about that.  With these workouts and my diet, I've lost 5 pounds in roughly 2 and a half weeks.  This isn't extreme but I'm inching towards my goal and nothing that I've done is unreasonable.
