Coach Notes
Body Screens
Pelvic Tilt
— player standing tall, natural stance
Anterior
Butt visibly out, lower back arched, belt buckle tilts toward ground. S-curve in spine.
Neutral
Belt buckle level, natural lower back curve, spine balanced. No exaggeration either way.
Posterior
Butt tucked under, lower back flat or reversed, belt buckle tilts toward chest. C-posture tendency.
Grip Position
— where the lead hand sits on the handle
On Top
Hand sits on top of handle. Few knuckles visible. V's point to chin or lead shoulder. Natural fade/cut.
Side
Hand on the side. 2 knuckles visible. V's point between chin and trail shoulder. Neutral shape.
Under
Hand wraps under handle. 3+ knuckles visible. V's point to trail shoulder. Natural draw.
Trail Elbow Fold
— watch first few swings, elbow at hip height backswing
Out
Elbow lifts away from body, points outward toward target line. Upper arm elevates with it. Steeper, more upright arm track. More external shoulder rotation.
Neutral
Elbow folds downward toward the trail hip, stays close to the body. Points toward the ground at the top. Classic slot. Most versatile delivery.
Behind
Elbow folds deep behind the trail hip, points backward. Flattest arm track. Natural inside-out delivery. Common with limited internal shoulder rotation.
Wrist Hinge Pattern
— hand club naturally, watch slow half swing takeaway
Vertical
Club goes straight up in takeaway. Wrist cocks up and down like a pump. Speed lives in the lever. Lever-dominant pattern — steep, early set. Hold-off release natural.
Combination
Club sets between vertical and around. Hinge and forearm rotation working together. Speed from both lever and body. Hybrid pattern — face opens back, closes through. Most versatile.
Around
Club rolls around the body, stays low and deep. Horizontal hinge — wrist rotates rather than cocks. Speed from pivot rotation. Pivot-dominant pattern. Bowed P4 natural output.
