Try releasing the right hand during impact.

I was taught this drill personally by Gregg McHatton, GSED.

You do not execute a correct Finish Swivel by 'releasing the Right Hand.' You execute a correct Finish Swivel by Rolling and Re-Cocking the Flat Left Wrist.

And that is how it should be learned.

Except in a deliberate Throwaway procedure or perhaps to a degree in a Right Arm Swing, there is no 'release' of the Right Hand during Impact.

There is a Release of the Cocked Left Wrist as the Clubshaft seeks its In-Line condition with the Left Arm, i.e., Full Extension.

There is the Release of the Turned Left Hand as it Rolls and allows the Clubhead to overtake the Hands.

And, for Hitters, there is the Active Release of the Bent Right Elbow as the Right Triceps straightens the Right Arm and drives the heel of the Right Hand against the Left Hand thumb.

But...

There is no release of the Right Hand, the Bent Right Wrist and the Clubhead Lag Pressure Point (Pressue against the forefinger).

Ideally, the Right Wrist is never Cocked (Perpendicular Motion) during the Backstroke -- so it cannot be Uncocked during the Downstroke. Instead, it is only Bent (Horizontal Motion) -- and that Bent condition is maintained through Impact and for as long as possible into the Follow-Through. There is no Flattening through Impact (also a Horizontal Motion) because any Flattening of the Right Wrist becomes Left Wrist Bend.

Throughout the Stroke, the Right Forearm Flying Wedge and its alignments support the Left Arm Flying Wedge and its alignments. And through Impact, it assures an On Plane Motion by Tracing the Straight Line Base Line of the Inclined Plane.

From the Top, the Right Forearm Flying Wedge only Rotates (Rolls to the left). The Right Wrist does not Flatten nor does it Uncock.The Left Arm Flying Wedge only Uncocks and likewise Rolls. Consequently, the Left Wrist never Bends.

Any other movement invites Horizontal Motion through Impact.

And that spells Geometric disaster.
