If you want to improve your power the best way I know how to do it from my studies is to first improve your strength. In their book, Rippletoe and Kilgore set up programming for this component. Once you have gotten fairly close to squatting, deadlifting, and bench pressing 1.1 to 1.4 times your body weight (according to David Sandler's numbers in Sports Power) then you want to start doing more speed and explosive work. While jump squats and plyometric push-ups are great exercises, if you don't have much in the way of strength you don't have as much potential to gain speed, thus increasing your swing speed. I think having strong forearms, fingers is certainly important though. As a fitness coach I had spoken to said: your body will not let you swing faster than your hands (are strong enough) can handle.
After having said all that, having periods of time where you lift explosively can improve your strength. If anyone has inquiries I can direct you to great resources.

The reason you can't sustain the lag is because you are so eager to make the club move fast (a reaction to the intent of "hitting it far"). So on a full shot you throw it away too early, which doesn't happen for your short chip. (bts)
I agree that flexibility is important but to be more specific, dynamic flexibility is probably even more important than static flexibility. With dynamic flexibility there is more careover to actual functioning. One thing I would encourage everyone that is looking for a bigger turn in the backswing to do is work on thoracic spine mobility rather than lumbar spine mobility. In other words, avoid this stretch: http://www.buildingbodies.ca/exercis...ck-stretch.jpg, and replace it with this stretch: http://fitnessforbettergolf.typepad....gression_3.jpg
The reason for avoiding lower back stretching is that in most people the core needs stability not mobility. In addition, hip mobility and thoracic spine mobility decrease the loading on the lumbar spine reducing the chances of lower back injuries. If anyone wants resources to working on these 2 issues that almost all people have I would be happy to include them.
Note the 2nd stretch (dynamic) can be done on all 4's as well. With the forearms resting on the floor and the knees bent to 90 degrees.
