The drill was done off a back stance, and the challenge was to perform a hip vibration - then send this motion into the arm. The arm is held tightly to the body with the lats, so that the forearm points directly at its target. 'Hip vibration' starts from the legs and the gluts. A movement is pulsed upward into the core of the body, and then transmitted into the arm. The arm is held tightly to the body by the pecs and lats. As the arm is 'punched' out, the legs snap back to their starting position. The movement does not have to be overt. It just has to pulse through the body and 'vibrate' a good mass of the body forward and back perhaps an inch or two. If you do it quickly that distance will visually appear much less - thus the term 'vibration'
Most beginners fire off the snap punch using the shoulder - negating the power that the legs can create. A roundhouse punch or a punch driven by the shoulder is different from this strike. There is no dishonour in using a roundhouse punch that requires shoulder rotation. There are advantages in raising the arm and cresting over the opponent's defence. But the shoulder rotation punch requires a good deal of muscle to create a good enough striking force. Not many people can get such power in a short enough time.
If you do the hip vibration however, the power of the punch will be phenomenal. It will seem like its going in slo-mo ... it feels effortless because there's no spike in shoulder tension. The secret is that you are accelerating a good portion of your body mass forward and then shunting it into the weapon of choice. The 'transmission' is done without much arm movement - in fact, the less your shoulder gets to rotate the better.
