Continuing the posture theme,I remembered reading this in Ori's Warrior Diet book. Ori's book is about intermittent fasting (specifically under eating for 20 hours and overeating for 4 hours - in the evening) but he does dicsuss other things such as training and posture.
Some elements of this fit with the model that I've been putting up here in recent days:
- chest not pushed out
- back ever so slightly bent forward.
