Yes, they are more workout options on the same DVD. For example, on the Gym Style Legs workout, there might be a "No equipment" premix and a "dyna band only" premix. These would use the exact same footage as the main workout, but the first one would skip all the exercises that uses equipment, and the second one would only play the exercises that use the dyna band. Other examples might be "extra long workout" where some of the parts from the main workout would be done twice. These are just examples (probably bad ones) that I made up off the top of my head. We don't know what the premixes are yet. Hope this helps!
