Early Extension: What Your Swing Video Can Show
Early extension describes the lower body moving toward the ball during the downswing. A useful video can show a movement pattern; it cannot by itself prove a physical limitation or the one change that will fix it.

From a video frame to a useful question
Original teaching comparison
From a video frame to a useful question- Setup record
- Club: __. Lie: __. Camera position and height: __. Target direction: __.
Keep these consistent before comparing two swings.
Case 1 - Visible observation
- Describe how the pelvis appears to move relative to its address reference during the downswing.
Use the same reference and comparable frames; avoid declaring a cause from one still.
Case 2 - Unproven explanation
- The clip alone does not show whether mobility, setup, intention, contact adaptation or another factor explains the movement.
Do not turn an observation into an injury or physical-screen diagnosis.
Case 3 - Next comparison
- Practice change selected: __. Reason: __. New observation: __. Contact and flight: __.
Choose one bounded change with an instructor and preserve the actual result, including no change.
Case 4
Original video-observation worksheet, not an analysed player clip, performed physical screen or before-and-after coaching result. No video was reviewed for this article.
The short version
- Early extension and early release are different descriptions.
- Keep camera position, club and reference frames consistent.
- Separate what is visible from the explanation you have not tested.
Name the movement accurately
TPI's written definition describes the lower body moving toward the ball in the downswing. Titleist's written introduction with Dr. Greg Rose also discusses pelvis movement toward the ball and a rising posture. Neither statement means that every upright-looking finish establishes an early-extension problem.
Early release or casting refers to a different aspect of how the club and wrists behave. Do not label both with the same word because a shot was heavy or thin. Describe which body or club relationship is visible, at which stage of the swing, before deciding what to investigate.
Make a comparable practice recording
Place a recording device safely outside the swing and ball-flight area. Note its position, height and direction. Keep the same club, target and lie when repeating a view. A changed camera angle can alter the apparent relationship between the pelvis, hands and address reference.
Look through the sequence rather than selecting only an address and finish still. Record the movement without estimating unmeasured degrees or centimetres. A two-dimensional view has limits; if the intended reference cannot be seen consistently, record that uncertainty instead of drawing a confident correction line through it.
Use the observation to choose the next test
Bring a repeatable clip and the contact or flight record to your instructor. The useful question is which explanation and practice change fit this golfer's evidence. A professional may separately assess setup, movement and physical capacity; this worksheet does not claim that any of those assessments happened.
Try one selected change in a safe practice setting and compare the same view and ball outcomes. A different-looking frame is not automatically a better shot, and one better shot does not establish a lasting correction. Do not force a position that produces pain. Persistent discomfort belongs with a qualified clinician rather than a diagnosis from this article.
