Trail Arm Retraction (90-Degree Turn)
Curated PGA Drill by Athletic Motion Golf
Backswing
3 sets of 10 slow rehearsal reps
Golf club, alignment stick (optional)
Intermediate
Why This Drill Works (Kinetic Mechanics)
Forces the trail shoulder into a retracted position before the full turn, ensuring the width and connection are established. This prevents the arm from collapsing and promotes a full rib cage and shoulder turn, which improves the overall structure of the backswing.
How to Perform the Drill
Follow these step-by-step instructions. Rehearse slowly to build proper motor patterns before adding full swing speed.

- 2

- 4
Step 4
Check: The shoulder should be positioned further behind your head with a straight trail arm, leading to a straighter lead arm and a full rib cage and shoulder turn.
What Good Feels Like
Focus on smooth tempo and maintaining body connection through impact. Your body and club should move as a single synchronized unit.
Common Mistake to Avoid
Rushing transition before completing backswing or lunging upper body forward towards ball at impact. Keep movement controlled.
