This short form is pretty simple to learn and I am trying it out for the next 100 days. (100 days is a common theme of practice in Chinese martial arts so I'm applying it here.)
Here is a video of the remarkable Mr. Fernando Bernall of Florida performing his version of the exercise.
It is also supposed to be useful for creating beautiful skin, a healthy spine, and regulating hormone levels.My personal experience so far is that after practice my skin and body are much warmer than usual. I'll keep posting information as I progress in my hundred days. We are currently on day two.
If you want to try out this program with me feel free to grab a copy of the book by Master TK Shih off of Amazon.
