Volume 23 in this series of 24 DVDs features Morio Higaonna performing the amazing Sanchin kata. The strength and power displayed by Master Higaonna performing Sanchin is phenomenal. Sanchin is a kata which is used to exercise the correct breathing techniques and the correct contraction of the musculature. Considered only from a technical viewpoint, the Sanchin kata is fairly simple, but to correctly learn and use its elements is truly difficult. It is an intimidating kata to learn at first. You are in good hands watching Master Higaonna painstakingly demonstrate Sanchin in his usual competent, relaxed way on this DVD.
