The Sanda class can be a good example of "no style" teaching.
A "no style" teacher may teach his class in the following way:
After students have learned all the basic tools (kick, punch, lock, throw, ground game), the teacher can created 8 (can be 6, 10, or ...) solo/partner drills of each if student wants to learn:
- power generation,
- speed generation,
- footwork,
- switch hands,
- attack through the front door,
- attack through the side doors,
- leading arm jam back arm,
- kick low, punch high,
- attack leading leg first, attack back leg afterward,
- use pull to set up push,
- use push to set up pull,
- use straight line attack to set up circular attack.
- use circular attack to set up straight line attack.
- attack one direction, you then attack the opposite direction.
- attack left, you then attack right,
- ...
In other words, all the principles, strategies, footwork, … can be taught/learned by a finite set of solo/partner drills. If those solo/partner drills are also recorded on video, the students will be easy to learn and remember.
