15-Minute Qigong Exercise for Activating Energy and Vitality - Strengthening the Kidneys.
I appreciate the primary focus is the stimulation of the kidneys which is not necessarily achieved by touching the feet per se, but by the action of bending the body forward. I also understand that different teachers have different views, so with that said:
How do you feel about bending the knees in this movement? Is it OK to bend the knees on days I can't touch my toes (old hernia injuries) or would I be better off keeping the knees unlocked and straight, keeping the structure and bending as low as is comfortable?
