Observed: Spine tilt measured ~36°, which is right in the ideal 15-45° band for an iron — nice forward hinge. However, your back looks rounded/hunched in the silhouette rather than flat, and your lead knee is almost locked straight (measured 8° flex) while the trail knee is at 37°. That's an uneven, slightly stiff lower-body base.

Good: Your hip hinge depth (36° spine tilt) is genuinely good and gives you room to swing. Stance width and ball position look reasonable.

Improve: Flatten the upper back so you bend from the hips, not the shoulders, and add matching, athletic flex to BOTH knees (aim for ~20-25° in each). A locked lead leg makes it almost impossible to turn your body — which is your core problem.

Observed: From address to takeaway the club moves but your torso barely does — the chest stays pointed the same direction and the motion is mostly hands and arms lifting. The head stays very steady (sway under 1 cm), which is fine.

Good: Steady head and the triangle of arms/shoulders stays connected early.

Improve: Start the takeaway by turning your chest away from the ball, not by picking the club up with your hands. Feel the lead shoulder move toward your trail hip from the very first move.

Observed: This is the heart of the issue. At the top your shoulders turned only ~14° and your hips ~6° (X-factor ~8°). For reference, beginners should reach 80-105° of shoulder turn. You are essentially standing still and lifting the club with your arms — the silhouette at 'top' looks almost identical to address. This is unchanged from your last session (also 13.9°).

Good: Excellent stability — head sway under 1 cm means you're not swaying off the ball, so once you add rotation you won't have to fight a slide.

Improve: You must rotate. Turn your back toward the target so your lead shoulder ends up under your chin. A bigger turn is the single biggest source of power and consistency you're missing right now.

Observed: Your tempo ratio measured ~3:1, which is textbook — so timing isn't the problem. But because almost nothing coiled in the backswing, there's no stored energy to transition; the lower body never loads or initiates.

Good: 3:1 tempo is excellent and well within the 2.5-3.5:1 target band — keep that rhythm.

Improve: Once you build a real shoulder turn, let the downswing start by bumping and rotating your hips toward the target before the arms come down.

Observed: With so little backswing turn, the downswing is again arm-dominant — the body stays bent over and fairly square. Hard to read path precisely in silhouette, but there's no visible sequencing of hips leading. Club detection suggested an upright shaft (~82° at address, ~74° in downswing) but that's unreliable here.

Good: Head stays behind the ball and steady — a solid foundation to build on.

Improve: Power needs to come from the ground up: hips rotate, then chest, then arms. This only works once there's a turn to unwind.

Observed: At impact your hips are only ~4° open and there's essentially zero hip slide toward the target. Tour players are ~40° open at impact; you're basically square with a stalled lower body, so the arms have to flip the club to square it.

Good: Great head position and stability — you're not lunging or backing up.

Improve: Get your hips opening to 30°+ at impact and your weight onto the lead foot. A clearing lower body lets the club release with much more speed and far better contact.

Observed: The finish is your best frame — you rotated through to ~54° of shoulder turn, got up onto the lead side, and held a recognizable finish with the club behind your head. Spine straightened to ~12°.

Good: You can clearly rotate THROUGH the ball and finish in balance — proof your body is capable of the turn you're missing on the backswing. Nice held finish.

Improve: Finish rotation goal is 75°+; you reached 54°. The bigger your backswing turn becomes, the fuller and more balanced this finish will get.
