@mariyadelano oh, i can't really praise my genes for many reasons, but on this topic I'm lucky. I don't stretch or do special routine. I usually have the "crepes" effect, i sketch and the first one is always bad, rigid, not in sync. Knowing it will be bad anyway helps me to just get into it without to much anticipation or expectations. It's certainly a warm-up necessary step. I try to get it done at breakfast, (but i'm bad at routine, more like chaos) so i feel ready for the day.
@davidrevoy do you think about your posture much? I notice in the airplane picture you're holding the tablet with the other hand and keeping it at a good angle
Do you try to keep your back straight?
