It is imperative to feel a flat left wrist and a bent right wrist as a player swings the club. It is also important to feel the pressure point one the trail hand index finger (part of index finger that touches the grip).
It is essential for players to deliver the grip end of the club past ball line on the way to impact. (See Tiger photo sequence)
The club head should never pass the grip end of the club in a fundamentally sound full shot.
This point is elusive and a somewhat of a secret that good ball strikers understand.
1 feature of bad ball striking is hitting on the collapse with an un flexed shaft…a hallmark of WEAK contact.
Players should learn how to properly pivot into their lead side while still feeling the club setting at the top of the b/s. This creates separation of upper and lower body movements.
If you try to emulate the pictures attached below you will never hit on the collapse!
