Part 1: Familiarising the Body with Different Attacks
Part 2: Accessing Natural Movement
Part 3: "Surfing" Your Body's Need to Survive
Part 4: Working from Physical Contact
Part 5: Feeling and Working from the Push Before it has Made Physical Contact
Part 6: Working Offensively
Before you can weaponise natural movement you first must be able to access natural movement. But REAL natural movement. This is what your body will do instinctively to keep itself intact, with minimal interference from your conscious mind. The opposite of this is contrived movement which stems from excess fear and tension. Natural movement is not so much something that you do, as much as it is something that you give permission to occur.
Once you have acquired natural movement as an ATTRIBUTE, progress to developing it as a SKILL, then APPLY it proactively.
Best of luck,
