Sorry, I don't agree with this at all. Based on physics, it should be obvious that pressing the bottom arm up will SLOW DOWN the swing - not speed it up. Pressing prevents your body from swinging. It may make the pole bend more, but it will kill your swing. The faster the swing, the more continuous the chain of motion - all the way thru the extension and flying off the top of the pole.

Exactly! This is the sensation that I've felt during the extension. I actually call it the "clean" part of the "clean and jerk", but same idea. "Dead lift" kinda implies that you do nothing after your legs and back are straight, whereas there's more to it than just the "clean" part. You still keep going - like the start of the "jerk" part, rather than end your body motion once the "clean" or "dead lift" is finished.
You can search for "kirk clean and jerk" for a fuller explanation of this technique. You'll find 13+ matches, and my 2 best descriptions of this are the ones in the "Bryde Bend" thread.
However, having said all this, I don't think this is ForBUBKA's problem. It's hard to tell without vid, but I suspect that it's 2 of the 3 things his coach says: He needs to jump up more and "sweep quicker". I disagree with the middle part though - "move the arms right away". There's nothing that needs to be done with the top arm except hang, and anything you cognizantly "do" with the bottom arm is going to alter the natural bend of the pole and alter your natural swing. Both no-nos.
The reason I didn't reply to ForBUBKA's post earlier is because I get tired of repeating the same advice time and time again. This is also why I now recommend that people search for my advice from (mostly) 5 years ago. Take it or leave it, at least my advice is persistent and has stood the test of time - for over 40 years now!
Petrov advice before Petrov! And Continuous Chain of Motion advice before Roman's 1992 article!
If you don't like my advice for whatever reason, then at least listen to Roman's Continuous Chain of Motion advice. It's spot on!
