The Magic of the Right Arm: Triangle Structure, Extensor Action & Power

Key Points

• Triangle Structure:

  • Arms form a triangle at setup — key for a connected, stable swing.
  • The goal is to keep that triangle intact throughout the motion.

• The Right Arm’s Role:

  • The right arm is always trying to straighten (this is called extensor action).
  • This natural straightening helps hold structure and keep the club in position.

• Why It Matters:

  • Right arm straightening maintains the connection between arms and club.
  • Prevents breakdowns or collapse during the swing.

• Two Motion Styles:

  • Swinging Motion: Right arm straightens passivelyMore fluid, effortless style.
  • Hitting Motion: Right arm is actively driven through the swing.
  • Adds force and intention to the strike.

• Both Styles Are Valid:

  • Whether you're swinging or hitting, the right arm remains active.
  • Choose based on your swing style and preference, but understand how it affects structure.

• Takeaway:

  The “magic” of the golf swing lies in the right arm’s instinct to straighten — use it to maintain structure, power, and consistency.
