David Blair of Swing Build Golf explains the critical 'chain reaction' created by a proper wrist hinge. He demonstrates how a flat lead wrist at the top of the swing ensures a square club face and prevents the common 'cupping' error that leads to inconsistency.
A proper wrist hinge creates a chain reaction where a small hip movement moves the entire club correctly.
The left wrist should hinge up on itself to stay flat or square at the top of the swing.
Forces should feel like they are working down the thumb and up the forearm bone for maximum stability.
Avoid 'cupping' the wrist, which Blair describes as 'floating' and highly unrepeatable.
A square club face at the top is directly linked to the alignment of the lead wrist.
