This relates to the only important position in the golf swing…Impact.
People talk ad nauseum about widening the swing arc on the backswing and at the top, but no one talks about getting it wide at impact. The lower your hands, the wider it is at impact.
Of course you don’t want to dive to get low hands ala Tiger Woods. I like the way JB Holmes does it.
People don’t like to get their hands extended, or low because they are afraid of hitting it fat. Fact is if you protect against this you can hit fat and thin shots.
Here is a video explaining this concept a bit. Like most things, don’t try and over do it, it’s just another way to look at proper release and allowing centrifugal force to get your arms extended through and after impact.
