Ok it's Day 5 now and I don't know about you, but I've started to notice that even I'm a bit slow getting started with the workout (cause I'm the best procrastinator on the planet), once I'm finished with the workout I'm actually ready to do more. I mean, it doesn't just get my heart pumping, but the moves and music and the choreography are challenging enough so that I don't get bored but also not so hard that I get totally frustrated.
