Full Definition
Forearm rotation (also called forearm pronation and supination) controls club face through impact. The trail forearm pronates (palm-down) while the lead forearm supinates (palm-up). Restricted forearm rotation leaves the face open (slice). Excessive or early rotation closes the face too early (hook). The GOAT Sling model teaches that forearm rotation is a RESULT of the body leading, not a conscious manipulation. GOATY WHIP gate measures the timing of forearm rotation relative to body movement.
