It's a toss-up, and will depend on what is on schedule for the day. If it's a cardio day, Kick Max will be my first workout to do. If it's a recovery day, then either core max or stretch max. If it's an upper body strength day, then maybe the upper body section of Muscle Max (I'm doing two-day splits right now), and if it's a lower body day, either the lower body segment of Muscle Max or the Lower body workout from the Gym Style series.
