Once in a high level pattern,restraining the top hand/back arm (avoid top hand dominance) and keeping the front side working well will demand a lot of conscious attention.
One golfer's warmup routine/similar to BP before game:
" I think it is helpful to begin warming up for a round swinging the driver as easily as possible, gradually working up speed until you play yourself into a tempo that feels about right.After you have found the right rhythm with the driver, try to carry the same beat down through the other clubs....if you are able to swing the driver easily and get good solid contact and good direction, it is more likely that on that particular day you will have better luck with your irons if you take the stronger club and swing it easily also. If you find that in driving it is necessary to swing hard in order to move the front side out of the way, the chances are that the irons will be better if the more lofted clubs are chosen and swung more nearly with full force."
