The grip should rest in your fingers from the middle pad of your index finger to the base crease of your little finger, not running through your palm. Your thumb should be down the top of the grip, just right of centre, the ‘V’ shape made by your thumb and index finger will point in between your right shoulder and your right ear. 2 knuckles will be visible on your left hand. Leave approx I cm from the top of the grip showing. When your hand is in the correct position, feel that you hold firmer in your little finger and ring finger.
Key to this hand is to see 2 knuckles visible. Start with your hand flat with your palm facing the target, point your fingers directly down to the floor below the grip. Similar resting position of the grip in regard of your fingers. The fleshy pad of your thumb sits on top of your left thumb so it can not be seen, keep pressure onto your left thumb during the swing. Similar to your left hand the ‘V’ shape made by your thumb and index finger will point in between your right shoulder and your right ear. The end of your thumb and the end of your index finger knuckle should be the same length down the grip.
Grip pressure should be 6/10. This pressure should be maintained throughout the swing. Too tight will cause thin or block shots as a result of not been able to rotate and release your hands and forearms. Too loose will cause all kinds of erratic shots due to lack of control.
I prefer the baseball grip for most beginners as all your fingers are touching the grip but as long as the above positions are correct I don’t mind.
There should be no gaps in your fingers and the grip.
Most golfers want to have a stronger right hand position as this feels more powerful, but unfortunately this will cause a closing (aim left) of the club face at impact, which will more than likely lead on to more errors to compensate.
