Loved the energetic effect of this. Would love to know more about the origin of this technique

Jenny S The beginning rocking comes from Bartenieff Fundamentals, which is a movement study that is often experienced in dance spaces but definitely not limited to them.  The moves that follow is a series that I've found works well for my body and was developed through exploration, trial and error .  :). Glad it felt good for you! 

I think PAT should have the option to watch the preamble in a seperate video for all workouts  or show us at what point the workout starts and make it easier to fast forward to that point. Preamble and introduction is important of course but when you do the same workout multiple times it can get frustrating.
