This is what Cathe posted a while back(before the filming):
Hi Everyone! We had a meeting this weekend regarding post-production of the new hardcore workouts and I'm happy to say that we will be including premixes on most of the workouts. There may be a few workouts which will not include premixes (ie: Stretch Max) but we will include them on all the workouts where it makes perfect sense to do so.
Hope that Helps, Wendy
