The dangers of very flat and one plane swings.

The bane of the existence of most mid to high handicap golfers and very strong and high speed golfers…is getting steep and/or narrow on the downswing.

That being the case, having a very flat backswing and/or attempting a one plane swing is a recipe for disaster and leaves you very low margin of error.

Matt Kucher not withstanding, having your left arm across your chest and below your right shoulder at the top of the backswing, is just asking to be steep, narrow and…bad at golf.

Now the devil’s advocate would say lifting too much and having arm over run is bad.

Well, it is, but like in politics, the ends of the spectrum can be dangerous and offensive.

I believe while a one plane swing may be more efficient on paper, it gives you no wiggle room.

The other point to make is if you give yourself some room to shallow the arms on the way down, you may stumble into a really good swing that many would consider one plane.

However, trying to thread the one plane pinhole (I have observed) can end up on the shanks and other bad shot patterns.

      Like I always say, why is a swing that took 10 years of 8 hour a day practice the standard?

      He had long arms like a monkey and little short legs.
      And he was great.

    Monte,

    Ive just gotten over this issue recently. I bought Jim Hardy’s book, which for me was the ultimate swingcrack. I was like Oh! I’m a one plane swinger that’s why I’ve been having issues… So I followed his book and it made things worse! Instead of worrying about where my elbow was and my arm at this point and so on, I focused on posture, making a good shoulder turn, and swinging in sync and things have improved so much! Thanks monte!

    Monte,

    Are you going to have a golf school?

      I basically have a traveling golf school. People can come to me, or I can go to them.

    “Threading the pinhole”. Physicists say that at impact the clubhead is a free body in space which would mean it is not controlled by the golfer. If that’s true then the clubhead must be released into space in a specific way to gain the best outcome at impact. I wish you would expand your comments on release. I think I understand it but I have some doubt.

      Physicists are all 28 handicappers who have sleepovers where they watch videos of pre-crash Hogan.

      no compensation or impedence allows a free release being possible on plane and to some extent you cant have any control over the clubhead at impact due to the force involved you created. if your off plane all bets are off.

        Thanks, Robert. 🙂
        It sounds like just take your best shot at the slot and there’s nothing you can do to increase your odds?

        if your on plane you can add speed as you will hit it solid in any case.
        problem with modern swingers even classic ones is that need to compensate to be on plane. same criteria applies tho. 😉

    Hey Monte,

    It’s been a while since I’ve commented on your posts but I’ve still been keeping up to date. I was wondering what you thought of my take away at the moment. I’ve always struggled with flipping the club inside and being way too flat and I thought it would be a good time to post this.

    Here’s a video:

    Thanks as always!

      Still a little flat with the arm swing, but looking good.

    ‘Control of cubhead at impact’….
    Get yourself a copy of “The Perfect swing” form the 1960’s…. they tested and showed that once the downswing is under way (from just after the transition) a golfer cannot change ANYTHING…. it’s all already decided.
    Chapter 17, an experiment in reaction time. You can obviously decide in advance of swinging to miss the ball, but they had golfers swing normally indoors, and occasionally the light would be rapidly extinguished at varying points in their swing (best to get the book, very good read…) – and when this happened the golfer was to try to miss the ball or alter their swing in any way they could…
    anytime shortly after transition all the golfers could not change their swing at all… and they also reported that they received the signal way later than reality (if i remember correctly.. not at home, can’t check).
    Raises some interesting questions… perhaps about intent ie don’t be thinking of that large lake in front of you just before you swing, or your body and subconscious is likely to find a way to hit the ball into it.. or for me, don’t stand up to a tee with a driver thinking about your nasty snap hooks with OB on your left…
    And how important it is to get yourself into position from your backswing and transition to make your swing.
    a lot of good stuff in the book… including some data and explanation of why the sample of pros they measured had head movement away from the target and downward… like Tiger’s ‘dip’.

      Personally I always thought anyone who focus on the technique side of an action that should be natural is teaching a slow down theory that likely isnt working in an easy way. Find out how to position yourself to be on plane and you can swing as fast you can.

    Is the Slicefixer method considered “one plane”? I apologize for the noob question, but I never really understood the one and two plane stuff. I remember watching one of those videos early in the 9-3 thread of one of his students and IMO, the backswing seemed so low and flat…..I would’ve asked, but I didn’t wanna get verbally flayed by one of his followers. So I just tried to emulate that move and it just lead to inconsistency.

    Good news is that I still don’t really care about the one/two plane stuff. My whole swing now feels a lot simpler. “Turn body in backswing. Let the club release naturally from top.” Haven’t messaged you with a question on GolfWRX in awhile, and that’s only because my swing has remarkably gotten a lot more consistent. And when I start pushing it out right, easy to fix. Mahalo for that!

    Still curious re: the Slicefixer swing, though.

    Aloha.

      Good to hear things are going well.

      I would consider that a one plane.
