Stream or download these complete form lessons with Master Chenhan. Learn the first three forms of traditional Chen-style Tai Chi with step by step detail. You choose how quickly you want to progress with the training, with a separate In-App Purchase (IAP) for each form as you’re ready to learn more. Lesson One: "First Form, Lao Jia Yi Lu, is the first form learned in Chen Tai Chi (or "First Road", Yi Lu, 陈氏太极老架一路). Chen-style tai chi can be traced back to the 1400's in an unbroken lineage and has become one of the most popular internal martial arts in the world. In this program, Master Chenhan Yang teaches you the first form, the standard 74-posture "Old Frame" (Lao Jia) Chen style, also known as the "First Road" (Yi Lu). Master Chenhan demonstrates the form multiple times, guiding you with step-by-step instructions and explaining the purpose of each movement. The postures of traditional Chen-style tai chi still possess their martial arts roots, but they are often practiced slowly as a form of gentle whole-body moving meditation. • Learn the form step by step, and understand the purpose of each movement. • Enjoy low-impact whole-body exercise, good for all fitness levels. • Master the popular 74-posture First Form for demonstrations and tournaments. Tai chi will increase your circulation, resulting in improved vitality and longevity, and it will develop your mind's alertness, awareness, and concentration. Most importantly, as you practice, pay attention to the feeling within the movements, so you may appreciate the profound essence of tai chi chuan. Lesson Two: Cannon Fist, Pao Chui, is the second form learned in Chen Tai Chi (or "Second Road", Lao Jia Er Lu, 炮捶 俗称二路). Chen-style tai chi can be traced back to the 1400s in an unbroken lineage and has become one of the most popular internal martial arts in the world. In this program, Master Chenhan Yang teaches you the standard 43-posture "Old Frame" (Lao Jia) second form of traditional Chen style, known as Cannon Fist (Pao Chui). Master Chenhan demonstrates the form multiple times, guiding you with step-by-step instructions and explaining the purpose of each movement. The postures of traditional Chen-style tai chi still possess their martial arts roots, but they are often practiced slowly as a form of gentle whole-body moving meditation. • Master the powerful Cannon Fist 43-posture form for demonstrations and tournaments. Lesson Three: Combine forms 1 & 2 with the standard Chen-style 56-movement form, with step-by-step instructions explaining the purpose of each movement. Chen tai chi is one of the most popular tai chi styles in the world, and it is practiced by millions of people every day. The movements still possess their martial arts roots but are often practiced slowly as a form of gentle whole-body exercise. • Popular 56-form for demonstrations and tournaments Tai chi relaxes the mind and body deeply, a key to maintaining and improving health. Your natural healing abilities are most effective when you are calm and centered. Regular practice can benefit your strength, flexibility, bone density, and muscle mass. The low-impact exercise has been shown to improve symptoms of depression and insomnia and promote the healing of chronic conditions. Tai chi is an excellent way to relieve stress, lower your blood pressure, and develop a positive attitude toward life. Thank you for downloading our free app!
