In this video, just like with Trikonasana, the palms face back and you continue the rotation as the arm is raised above your head.
With all postures check:
Do yo have a full journey in and out?
Do you feel any pain or discomfort?
Can you feel any crunching anywhere?
Exactly where do you feel the stretch?
Is it a stretch or is it tension?
Can you take a full breath of air?
