Very interesting video for anyone out there that is interested in throwing a punch that an opponent will find difficult to see/stop.
The message of this video is basically to flow the whole punch in one motion. Do not telegraph a punch by pushing off from your shoulders (whip lash effect). Instead move your body (legs,back,shoulders and arm) with the whole punch as one AKA everything happens in one big flow. Your opponent will not see your punch coming and will not be able to stop it.
Part 2 for anyone that is interested.
