I have noted that most pro golfers use a neutral trail hand grip - even if they use a very strong lead hand grip, and I have often wondered why they make this choice. I now realise that when the right elbow bends, it is easy for the trail palm to become parallel to the swingplane by P2.5/P3 by varying the amount of trail forearm supination and/or trail wrist circumduction happening during the takeaway.
So, consider Daniel Berger's takeaway.
So, consider Daniel Berger's takeaway.
Image 1 is at P1, image 2 is at P2 and image 3 is at P2.8. The two palms are not parallel to each other at address.
DB uses a very strong lead hand grip so the back of his lead hand is roughly parallel to the swingplane at address. Then, during his takeaway, he does not have to roll his lead forearm in a pronatory direction very much to get the back of his lead hand parallel to the swingplane at P2 and P2.8. That means that the club handle is not rotating clockwise very much between P1 => P2.8. To get the trail palm parallel to the swingplane at P2 and P2.8, he does not have to roll his trail hand very much - note that he bends his trail wrist back without appearing to having very much trail forearm supination or trail wrist circumductory roll motion happening between P1 => P2.8.
Now, consider a pro golfer who uses a neutral lead hand grip combined with a neutral lead trail hand grip - Adam Scott.
Image 1 is at P1, image 2 is at P2 and image 3 is at P2.8. The two palms are parallel to each other at address.
Note that AS has to pronate his lead forearm in order to get his lead palm parallel to the swingplane by P2 and also at P2.8. Note how much he has to supinate his trail forearm +/- have an element of trail wrist circumductory roll motion to keep his trail palm parallel to his lead palm during that same time period. In particular, look at how his trail palm is already facing skywards at P2 due to a lot of trail forearm supinatory motion - compared to DB at the same P2 position, where the the degree of trail forearm supination appears to be less. However, by P2.8 they may/may not have a similar amount of trail forearm supination depending on variations in the degree of trail wrist circumductory roll motion happening during that same time period - presuming that they are both on the same swingplane steepness at P2.8. I therefore conclude that it is biomechanically very comfortable for a pro golfer to use a neutral trail hand grip - irrespective of the strength of the lead hand grip - because small variations in trail forearm supination +/- variations in trail wrist circumductory roll motion can accommodate for any variations in lead hand grip strength.
