3 Functions of Your Right Arm in the Golf Backswing


Published: March 2, 2026

In this video, I'll show you the 3 functions of the trail arm in creating the perfect backswing position.

You'll find out:

  • How to properly use your core muscles for an efficient and under-control backswing rotation,
  • How to eliminate a shallow arc in the backswing by freeing up your trail arm, and
  • Why the famous “towel under arm” drill can destroy your swing.

The trail arm plays a critical but often misunderstood role in shaping your golf backswing. When it’s properly freed up — rather than pinned to the body with a towel or similar constraint — it allows the club to set on plane naturally at the top, giving you a much steeper and more powerful downswing plane. Constraining the trail arm artificially prevents the shoulder turn from loading fully, costing you both width and depth in your swing arc. See exactly how your trail arm is moving at the top by running your swing through an AI swing analyzer, and ingrain the correct backswing mechanics with structured repetition in the GOAT Drill system.
