It doesn’t take a genius to figure out what’s wrong.
It takes even lesser to confirm the finding.
I took one look at how my student was performing Push and pointed out that its not strong.
A simple test of the power of push on a partner soon proved the veracity of my observation.
The posture is a problem, rendering the power weak and potentially can cause one to lose balance.
How to fix it?
If there is a problem with power generation and balance the root cause inevitably lies in the stance. This is why I would advocate careful study of Beginning Posture because the key principles are there.
Once the primary principles are understood then one can move about when playing the form with good nimble balance and power.
The same principles that I taught can be seen in the screen shot below of Grandmaster Dong Huling in the Push posture.
The posture of Grandmaster Dong exhibited compliance not only to the principles of the Tai Chi Classics but also to physics. If you are not sure what I am referring to just refer to any textbook on Physics particularly the chapter on mechanics.
You can view an example of how mechanics is used to analyze movement in sports here – not to worry if you have a problem digesting the article as fortunately in mastering Tai Chi we do not need to understand the mathematical models underlying human movement. As long as you can feel your own body you should have no problem feeling what is the right thing to do.
