Executing a perfect golf swing is simple if you know how many times to unlock and relock your lifeline/thumb connection.
One way to execute a perfect golf swing is to unlock and relock your lifeline/thumb connection twice— and no more.
If you want to hit the golf ball straight you should learn more about the lifeline/ thumb connection.
First of all, allow me to explain the lifeline/thumb connection.
When you grip your club with either an interlocking, overlapping or baseball (ten fingers) style of grip, you should complete your grip by docking (locking) the lifeline of your right hand squarely and securely on your left thumb if right-handed and, just the opposite if left-handed.
The lifeline is the channel that runs between the thumb and palm pads of each hand.
Thus, when the lifeline of the right hand is locked on the left thumb I refer to it as the lifeline/thumb connection.
The number of times the lifeline/thumb connection is unlocked and relocked, once the grip is completed, will have a significant impact on the direction and pattern your ball will fly, whether you wish to work your ball or hit straight golf shots.
Here is what occurs when the lifeline/thumb is initially locked.
When using either an overlapping, interlocking or baseball (ten fingers) type of grip, the instant you complete your grip your elbows will rotate to the inside of your shoulders to create an out-to-in swing path of your clubface.
Also, your wrists and clubface will rotate to an open alignment, all of which will temporarily establish a slice ball flight alignment.
However, such slice ball flight alignment is not locked-in.
This means any subsequent body movement will rotate the alignment and swing path of the clubface to a different ball flight alignment, all unknown and undetectable by the golfer.
This is the very reason why the ball will often fly in a different direction and patterns even though the club is swung the same with each subsequent swing.
Notwithstanding, if you unlock and relock your lifeline/thumb connection a certain number of times immediately after assuming your grip (before there is any other body movement), you will be able to lock the alignment and swing path of your clubface to a specific ball flight alignment.
For example, if you unlock and relock your lifeline/thumb connection twice after gripping your club and, before there is any other body movement after your grip is completed, you will rotate your elbows parallel with your shoulders to lock-in an on line swing path of your clubface.
Correspondingly, you will rotate and lock-in your wrists and clubface to a square alignment, all of which will lock-in a straight ball flight alignment.
I refer to this golf method of locking-in a straight ball flight alignment during the setup proceedings as the Triple-Crown Golf Technique™.
Once the Triple-Crown Golf Technique™ is performed, you must not thereafter unlock your lifeline/thumb connection,
Then it is just a matter of assuming a comfortable stance and posture to your ball, centering the sweet spot of your clubface as near as possible to the back of your ball, aligning your shoulders parallel with your target line, maintaining a steady head and executing a simple golf swing.
Then watch your ball fly dead straight in line with your target, discounting wind conditions and elevation differences between your stance and your ball.
In doing so, you will experience the perfect golf swing.
More detailed instructions and trouble-shooting tips to perform the Triple-Crown Golf Technique™ are addressed in one of my instructional books, How To Lock-In A Perfect Swing.
