Over-Swinging
What is actually happening
You're chasing distance the honest way, with a bigger swing. The problem is your swing kept going after your body finished. Once your shoulder turn completes, the arms keep traveling on their own. Posture gives a little, wrists collapse a little, and the top of your backswing ends up held together by parts that stopped turning a beat earlier.
What it costs you
The camera plays the same trick on everyone: the longer swing feels faster and measures slower. The extra length shows up with bent arms and borrowed posture, the downswing scrambles to gather it all back, and your contact scatter doubles. A shorter swing that keeps its shape beats a longer one that loses it. Every time.
The backswing ends when your lead shoulder finishes turning. Your arms stay in front of your chest the whole way.
Three-Quarter Rehearsal
Make swings that feel three-quarter length and let the camera prove they're full. It will, every time, because the swing that feels short to you is usually the one that stops where your turn stops. Hit five balls at that feel and film each one. Watch the shaft at the top: what felt like three-quarters will sit at or near parallel, with your lead arm still long and your posture still intact. Keep hitting balls until the feel and the film agree. You'll tighten your strike and lose nothing off the tee. Most players actually gain yards, but don't take my word for it. The video settles the argument.
