Hello all,
I recall Dani asking about this punch a while back, and I forgot to post about it. Lamar can explain this much better than me. Basically you're working to get knockout power from your power hand (right for most people) even though you have it to the front.
Here are a some basic points.
1) It's thrown with a verticle fist.
2) You use "body torque" for extra power, being mindful not to "overrotate"
3) The punch never "stops". Unlike a jab that goes straight out and straight back, the straight lead goes through the target and returns with a "shortened arc".
4) It can be thrown with or without footwork.
5) Use good "elbow in" structure like you would with a Wing Chun straight punch.
Those are the points that immediately come to mind. Everyone feel free to chime in and "fill in the details".
Oh, getting "knockout power" from a lead punch didn't begin with Bruce. Jack Dempsey could also do this. From what I recall Bruce was an avid fan of Jack Dempsey's ideas. Here's an online version of Dempsey's book "Championship Fighting".

All of the chapters are good, but "falling step", "power line" and "shoulder whirl" chapters are particularly interesting to me with respect to lead punching.
