From your stance, drop your right foot flat, toe perpendicular to your target- you want the right side of your body in a straight line, as close as possible. You use the muscles on the right side of your body to torque your left side around; this causes your left foot to pivot. The left foot pivots on the toe, the leg turns, the hip turns, the shoulder turns. Your keep your left shoulder in its original position as long as possible, and the tension you are creating causes it to turn, whipping the fist through the target. Turning the weight in front of the punch creates a whip-like effect and concussive force.
What Weldon is showing is damn near useless. Many years ago I bought one of his training videos and wasn't impressed with the way he taught punching. Then I saw a fighter of his- Weldon had started him, and he was undefeated. Punched just like Kenny taught in the videos and he couldn't hurt anybody with his fists, bad luck for a prize fighter.
