Adam Porzak and Mike Pitt of Porzak Golf address a common misconception regarding trail arm connection. They demonstrate the 'giving blood' setup position to promote external rotation, ensuring the trail elbow stays in front of the body to maintain width and a proper swing plane.
Connection is defined as keeping the hands in front of the sternum, not pinning the arms to the ribs.
The 'giving blood' position involves externally rotating the trail elbow while maintaining an independent, neutral grip.
The trail elbow should never get behind the side seam of your shirt during the backswing.
Proper trail arm structure forces the body to turn more effectively to reach the top of the swing.
Pointing the trail arm's 'funny bone' (ulna) toward the ball at setup helps set the club on the correct plane.
