In this clip we are practicing the use of Wild Horse Parts Mane. The point I wanted to make it that because of the arm’s angle its more difficult to inject forceful power into the technique.
What we didn’t practice here is the full technique itself as our focus was on the use of intention and relaxation to generate power. At 1:00 I used momentum to generate the power. Contrast this with the use of Peng and An force beginning 3:10 and how the use of intention added to the sharpness and forcefulness of the technique.
