Grip chat (boring thread) | Golf Monthly

So you can get the same range of movement whether you've got a good left hand grip or a bad one?

No, you can't get the same range or correct motion with a bad grip, either in one or both hands.
(there should be no flip of the hands/wrists anywhere in a golf swing)

You never want to 'hold' the club in the 'palm' of the left or right hand.

Holding the club mainly in the palm of the left (RH golfer) won't allow the left hand to 'cock' in the correct anatomical condition and will limit the amount of movement, so limit the club-head speed (& accuracy) your swing motion would be able to produce with a correct grip.

Simple check you can do to feel this is;
With the club in the wrong position in your left palm, simply with this palm positioned left hand only on grip (right behind your back)
From address slowly swing and turn to the position in your backswing when your left arm is parallel to the ground, (no cheating by relaxing, letting go or changing from the palm grip during this move!) and you'll see it's impossible to get a 90 degree "L" shape between left arm and the left wrist & club shaft, it will be a lot less than 90.

The handle (grip) of your club should run from the crook you form in your first finger, diagonally across from it so the butt end is under the fleshy pad in the palm of your left hand and not directly under your thumb, so you'd feel this pad is on top of the grip, the left thumb lies vertically down the top right side of the handle. Then you just close the rest of the fingers around the handle.

The 'snuff box' joint (radial fossa) on your left wrist is the fulcrum for the upward left wrist cocking motion and at address this should be atop of the grip (analogy: if you were able to push a pin through this snuff box it would go straight into the topside of the handle, pin wouldn't miss the handle left or right.)

Here's good instruction for getting a good grip. (& the arm by the side while taking the left hand position is the way you'll always see Adam Scott start to form his grip).

This is the link to the left hand grip after you've watched that a few times click on the name (Larry Hamilton Golf 6 videos) and you'll see the video for the 'right hand grip' too.

Hope this is of help.
