By clicking PAYMENT, I hereby release Inner Research Institute (IRI), all instructors and all other students of IRI, for any and all liabilities for any type of injuries or loss sustained while training, studying, practicing, or in the application of T’ai Chi.

Yang Style T’ai Chi Ch’uan Short Form

As created by Master Cheng Man-ch’ing

T’ai Chi classes at IRI emphasize development of the ch’i with respect to Traditional Chinese Medicine. The purpose and goals of the school are to teach and develop the art of T’ai Chi Ch’uan as a tool for improving one’s health. Through the understanding of one’s ch’i energy, one may embrace more fully life’s treasures of harmony and happiness.

The Inner Research Institute teaches the sequence of the short form of the Yang Style T’ai Chi Ch’uan that Master Cheng Man-ch’ing created. Push hands, San Shou and the T’ai Chi sword are also practiced throughout the year. IRI was founded as a nonprofit organization in 1970 on the island of Maui in Hawaii. Since its origination, IRI has successfully taught T’ai Chi Ch’uan to thousands of students from the US, Europe, Russia, Australia, and Asia. Our hope is to seed future generations of students and teachers to perpetuate the legacy of our lineage.

Martin Inn founded the IRI and has taught T’ai Chi Ch’uan for over 50 years. With Benjamin Lo, he is the co-translator of The Essence of T’ai Chi Ch’uan and Cheng Tze’s Thirteen Treatises on T’ai Chi Ch’uan, two books have become standard texts for students and practitioners of T’ai Chi. Martin is also a licensed practitioner of acupuncture and Chinese Medicine in the states of California and Hawaii, and is certified by the National Commission for the Certification of Acupuncturists. He holds an OMD from the Postgraduate Institute of Oriental Medicine in China and has been in private practice for over 40 years. In 1992, he founded a teachers’ apprenticeship program at IRI and certified those leading classes today. IRI’s teaching cohort continues exploring greater depth of practice in periodic teachers’ workshops with Martin.
