Re: Breathing Exercise and Meditation
Yes, but our shihan only explains it once a year at the yearly koushukai. I seriously doubt people are paying attention. So when we do the exercise during warmups, I have noticed that most aren`t doing it correctly. So maybe the answer to your question is also no.
While sitting seiza, we reach up with both arms, streching up and breathing in. We make fists and bring the arms down to where our fists are about to our ears, holding the breath, and focusing on our lower abdomen. Then we breathe out while lowering our hands.
I`d say our style is pretty conservative Aikikai Honbu.
