The truly internal fajing process has a lot of small refined movements involved. If you get them wrong then you end up with a push, not a forceful explosion of power.
In this clip you see my student trying to learn the process. Definitely not easy to do. But if you love a good challenge….
The challenge of doing Tai Chi internally is the ability to have laser-like focus on what you are doing as well as the ability to keep the mind honed it on applying the intent to drive the movement.
In this clip you can see how by adding intent I can make a tap with the fist hurt more.
