Forming the fist : punch down and brush knee punch

The coordination of brush knee punch downwards is timed with the stepping leg. The fist should not be formed too early. Every movement is timely. When deflecting and sticking the hand does not begin to form the fist. When stepping the left wrist is substantial as you stick to your partner, as the substantial feeling moves through the leg as you shift your weight, the puch is formed and the force increases as the weight shifts.

In brush knee push, again it is the hand that brushes the knee that has a substantial force during the step. The force for the push arrives during the weight shift. When the shoulder relaxes the elbow feels substantial as the hand moves forward. The downward movement of the elbow creates a spiral to the hand movement.

The spiral force moving through the forearm is common to many postures although has different functions - not always when a force moves through the arm to produce a strike.
