The Magic Triangle, every swing
The triangle between your forearms and chest is the foundation of every great swing — Hogan called it the Magic Triangle. Lose it, and you lose leverage, compression, and consistency in the same instant.
theSTRUCTUREBALL sits between your forearms and locks your upper arms to your chest. The instant your arms try to separate from your torso, the ball pushes back — you feel the disconnect immediately, on every swing.
Within 20 practice swings, your body learns to keep arms and chest moving as one unit. Maximum leverage. Maximum compression. A swing that repeats.
