In the following clips, you can see a lot of solo drills left and right. If you just pick up any drill and try it yourself, you will get a feeling about "power generation" that you may not have felt before. A good power generation system doesn't need many years to learn. If you just try it for 2 weeks, you should have some good feeling for it. The more that you watch these clips, the more that you will fall in love with TCMA.
Some people may say that you will need an "internal body" to be good in "internal". Just by repeating these drills, you can develop your "internal body" whatever that suppose to mean IMO.
If you look at the 1st clip from 0.01 to 0.16. It's just a simple downward strike. You can see that his whole body is unified as one single unit. When he moves, all body parts move. When he stops, all body parts stops. Also you can see that his body is moveing along with his arm and not just moving his arm without moving his body.
Also interest "pull your opponent arms apart and headbutt" start at 1.24 that you just don't see it commonly appears in most TCMA forms.
I'm not trying to encourage "youtube learning" here. But if you try it, you may have a new opinion about TCMA.
Would you like to take one of these drills and drill it for 2 weeks and share your result and feeling here?
