Attending class once a week will allow you to learn the form in a basic way that will enable you to practice Tai Chi as a health and centering exercise.

Attending class twice per week will enable the student to learn the form in a more detailed manner, significantly developing healing and regeneration; meditation of the form develops, and increased physical conditioning results.

Attending class three or more times a week provides the student with a form that is highly conscious, and develops a significantly important level of embodiment of the “internal principles,” which are essential for comprehension (Understanding) of the higher levels of the art of Tai Chi Chuan. At this level of practice, significant transformation and development of the body, emotions, mind, and Spirit occur.

Tai Chi Berkeley offers private classes by appointment.

Class Descriptions

Level I – Beginning: The first class in the twelve week session introduces Tai Chi and its various ideas and benefits. A five part warm-up set is taught in the first class. Students who continue in the course develop the initial warm-up set, then begin to learn 2-3 postures (form positions) each week. By the end of the course students have learned the first half of the form. These postures are designed to create optimal external alignment to facilitate stability, strength, and flexibility by conscious organization of bones, joints, and muscles. Some internal Ideas and Principles are introduced.

Level II – Form Correction and Meditation: This course focuses on increasing awareness and depth of the postures learned in the beginning course, as well as strengthening and increasing Chi (internal energy) flow and development. Introduction and practice of the Standing Meditation connects the Body (inside and outside), the Breath, and the Mind to nurture and fortify internal organs and related systems through development of Chi.

Level III – Intermediate: This twelve-week course adds more advanced form postures to those learned in the Level I course and refined in Level II. Continuing to work with the specifics of postural organization, the student learns increased awareness of internal alignment concepts, which begins to significantly affect internal organ health and development, and energy flow. By the end of this course, students have learned the complete Tai Chi form.

Level IV – Advanced Form Correction and Meditation: These ongoing classes significantly deepen the form work, with more focus on conscious details, working to embody the five Basic Principles, and setting a foundation for a continuously expanding developmental process to unfold. While cultivated practice of the Level II meditation can be sufficient, the Standing Meditation practiced in this course cultivates increased internal focus, further developing and refining the Chi, and significantly strengthening internal organs.

Level V – Push Hands (Beginning and Intermediate): Push Hands is a fundamental tool used for martial art training in Tai Chi. It is practiced at various levels. Most people think of martial arts as fighting with an opponent. That, at some level, can represent part of the truth; another important part of the truth is that martial arts represent how you deal with things when they come at you, whether the thing coming at you is a person, Life, or yourself. Through the cooperative-competition of push-hands, we explore and work with issues such as reactive resistance, activity without aggression, receptivity without weakness, and how to neutralize and not be impacted or imbalanced by an incoming attacking force. After these skills are significantly developed the student can choose to learn push hands as a Tai Chi Chuan martial fighting skill, with application and more dynamic practice. As students learn martial skills, they are very much encouraged to learn Wu Te (martial virtue), how to treat the Art, the Teacher, classmates, others, and the self, with respect and value.

Weekly Schedule

Class sessions are 12 weeks long, and are offered four times per year. Session dates can be found below.

In-Studio Class Schedule

Lenzie teaches Advanced classes (Level IV and Level V), with occasional substitutions by his Senior Student Instructors. Beginning and Intermediate classes (Level I, II, and III) are taught by Lenzie’s Senior Student Instructors.

No application/pre-registration is required for in-studio classes.

For in-studio classes, the following COVID-related protocols apply:

  • Wearing masks during in-studio FORM classes (Level I through Level IV) is optional; however, wearing masks during in-studio PUSH HANDS classes (Level V) is REQUIRED. Changes in “COVID-19 Community Level” or in Public Health guidelines have resulted and may in the future result in changes to the school’s policy.
  • When required to wear masks in the studio, participants may choose between wearing a well-fitting surgical “procedure” or cloth mask, or a more protective N95 or KN95 mask. (Masks with valves do NOT meet this requirement: masks that have valves are not protective against transmission of COVID-19.)
  • All in-studio participants must be fully vaccinated (including the two-week waiting period after your final vaccine dose) BEFORE your first in-studio class. CDC-approved boosters are strongly recommended.
