Thanks so much, Richie.
I actually mapped the video out for each of the 19 exercises and have been doing the 1,4,5 for each one. Quite exhausting to keep track and do, so have done about 10 of the 19 exercises a session. I can see how it will be easier to establish a given combination like Lower DT NT 3 and b7 as a unit and then practice in all directions.
