Speaking from a teaching or instruction point of view, let alone deciding to swing using a certain model, the very first question about a golf swing model should be, “Is it mechanically-sound?”
The answer to that question with any iteration you choose to pick from the Modern Golf Swings out there is simply and concisely, “No,” which means it shouldn’t be used for the purpose of swinging a golf club.
This is because, as we know, the Modern Golf Swing principles promote restricting the hip rotation on the backswing while twisting or torqueing the lower back to complete the shoulder turn.
Modern Golf Swing Example
This means the very thing that makes a Modern Golf Swing a Modern Golf Swing is a principle which is not mechanically-sound, thereby causing unnecessary damage & injuries to the back and other body parts.
Strike 1. (And really, this 1st Strike ends the game without the need for the other 2, but let’s do it anyway…),
This principle (restricting the hip turn) would also overly complicate the generating of natural and powerful leverage in a golf swing, because the natural action of a shoulder turn is actually powered by the hips & legs.
Lastly & importantly, you will not generate more speed nor produce more accuracy or repeatability with a Modern Golf Swing, as you contort yourself into one pretzel after another in trying to master swinging a golf club with a restricted hip turn.
So, you not only will damage your body, incur injuries and interfere with the natural production of leverage, you will struggle to do it consistently and with accuracy.
There are many and various reasons why someone may prefer swinging along the principles of a certain model (say, wanting to emulate Jack Nicklaus’ or Ben Hogan’s swing models), usually coming down to a belief in power, consistency or accuracy reasons.
You should never, ever try to emulate the swing of a certain type just because you admire a player. If that player is swinging with an improper model in terms of mechanical-correctness, you’ll be setting yourself up for heartache (you’ll never master a tailor-made swing suited to one player and that player only) and back-ache.
It’s as simple as that.
The closer to mechanically-optimal a swing model is, trust me – the easier it will be to understand, learn and implement.
As with any athletic motion.
