In Summary:

Check your setup: Many players set up with open shoulders, leading to shallow hand paths and poor shots.

Square up your chest: Position your chest slightly closed behind the club head to facilitate a deeper backswing.

Importance of rotation: Squaring the setup aids in better rotation and aligns hands with the trail shoulder.
Avoid arm-driven backswing: Don’t let arms dominate; keep arm structure aligned with the torso to prevent casting.

Ideal hand position: Hands should be in front of the torso during the backswing, not passing it.
Key tip: Setup and hand-torso alignment crucial for consistent and effective golf swings.
