Schedule Changes

We’re making a lot of changes starting May 1: adding new classes, moving outside in Boulder on Tue eves for the summer, and relocating a number of classes to Hygiene. This is really exciting: it lets us offer daytime classes and more opportunities for deep study! Check the Class Schedule for details.

There are several new classes:
* Sword on Wed morn at 9:30 am
* Full form on Fri aft at 1:30 pm (beginning May 1)
* Open Studio practice on Fri aft from 2:30 pm - 6:30 pm (beginning May 1)

Our current beginning form class began on Mar 20 and will run 14 weeks through June 19. Our next beginning class will be in the fall.

Contact us to be put on our mailing list so you get notified about that class.

First Sunday

Our next First Sunday class will be on May 5, at our Hygiene Studio.

Form from 10am - noon. Sword or Push Hands from 12 - 1. Open to all RMTCC students who have learned the full form.

Lee's Latest Translation Effort

I recently finished a translation of the 7th Treatise on Jin and Physics from Professor Cheng's 13 Treatises.

This translation spawned a lot of additional work as I tried to understand the cultural context in which Cheng wrote this treatise. I’ll share my results shortly in another piece.

But, for now, you can peruse Cheng’s ideas about the mechanics behind Tai Chi Chuan.

You can find all my translations on the Translations page.

The Yang Family Eight Word Formula, freshly translated into Spanish thanks to J Félix Fernández.


We base our work at Rocky Mountain Tai Chi on the "practice tripod" defined by Professor Cheng: form, push hands, and sword.

We also incorporate practice of various qigong sets, fundamental drills, standing meditation, and internal work.
