In my experience, I got a lot more out of my professional golf instructions when I had some sort of clue what the PGA pro was talking about. If I simply went into the professional instructions blindly, then I would spend a lot of money simply by reaching the same point I could have achieved by initial self-study.
From the top of the backswing, you should swing the golf club down with your arms and not your body. Turning your upper body too early is what causes an over the top move in the swing. If the upper body or back stays facing your target a bit longer, the golf club can swing down properly more from an inside path and you'll be able to square the club up coming into impact much more easily and effortlessly.
In order to achieve true disconnection of the lower body from the core, the legs must be strong enough to support the upper body while it rotates. More times than not, if the legs are not strong enough it will begin to sway or rotate along with the core.
When working on your full swing on the driving range, there are a few helpful tips that will allow you to be more successful with your game. First of all when you are on the range, you should always have a target you are hitting towards. Whether it's a flag, a tree, or bunker, it's very helpful and necessary to know where you are trying to hit your golf shots.
Golf carts now come in all sorts of high tech models. They are motorized and are now capable of remote control, just like your remote controlled toy cars of childhood. It sounds very convenient as now you concentrate more on your sport than toting around heavy golf clubs half the time.
Coming over the top will generally lead to a pull or slice golf shot pattern. This improper swing path causes either of these problems depending on how the golf club face is at impact. Learn how to swing the golf club more from the inside as you approach the golf ball and you'll hit straighter golf shots.
Work on a change or adjustment with your golf swing on the range until it becomes more comfortable and natural. The driving range is where you want to focus on your technique and any adjustments you may be making with your golf swing.
