Simple Shoulder Plane Drill (Fix Flat Turn)
Drill by RotarySwing.com Golf Instruction
Why this drill works
The shoulders must always rotate perpendicular to the spine angle to maintain proper posture and the swing plane. A flat turn (shoulders parallel to the ground) destabilizes the spine and forces the club out of position, requiring timing-dependent compensations.
How to do it
- 1
Place a golf club across your chest, resting on your shoulder sockets (butt end on the left shoulder, sticking out).
- 2
Backswing Check: The club should point down toward the ground, slightly outside the ball, not parallel to the ground.
- 3
Visualize the 'T': Maintain the 'T' shape formed by your spine and shoulders; your shoulders must rotate perpendicular to the spine angle.
- 4
Feel: Focus on the sensation of your left shoulder pointing down toward the ground.
- 5
Use a mirror to visually confirm the perpendicular rotation.
