The action of creating a lag within the driver golf swing should help you produce more distance. That is because, as previously mentioned, as those wrists remain hinged in that cocks position there, and they move out into the point of impact, it’s this store up of energy as you move through the ball, that will release the club head into impact.
But the whole point of this is that it stores up potential club head speed. If you are looking to improve your distance, that is what you need. You need a centered strike and you need more club head speed. So storing up that lag and delivering it down into impact, that will help produce that speed.
However, because you are starting to get more lag and because you are moving into a position coming into impact with that wrist nice and hinged in this lag angle position. If you simply maintain that lag angle, that stored energy in between the hands, the club and the wrists will not produce more speed, will not produce more energy unless it is released through.
If you simply continue to hold the angle all the way thorough impact, there will be no energy release down into the golf ball. So this is where practice and this is where working on timing really comes into play. It’s actually moving through the point of impact. Yes, increasing lag angle should increase potential club head speed but it is from this point here, down into the point of impact that those wrists need to unhinge and unwind into the ball.
A very simple way of practicing this is the hold lie angle moving in, and then as you get to this point in position, start to release that angle through. If you can get just on the driving range, you use something like this drill, then hopefully you can start to store that lag angle up and produce more speed throughout the shot.
