Randi - As most Beachbody productions, they are geared for beginners to advanced. Usually they have different people doing the advanced, beginner version, etc. The basic set teaches you the moves and the workouts are a bit shorter and the advanced set (which they offer in the upsale process) are longer and slightly more intense. They are not Imax intense though! I was able to get my HR up to 150 or so which is the higher end of my zone.
