Went ok with this. Found the standing stretch slightly more difficult than the lying oblique work.
Need to concentrate on keeping hip facing forward and pushing shoulders for the standing.
Felt like the lying was per the video, with the shoulder only slightly lifting from time to time, and just a matter of concentrating and lowering it flat again.
Decided to follow up with a week 1 session - chosen by rolling a die - got a 3 Intro to wrist mobility - I like that one.
I need to consider a way to track my progress.
