There are really six basic golf swing fundamentals that need to be learned, and managed whether you’re a beginner or a pro.
The Grip
Simply put the grip is just how you hold the club in your hands. There are three regular grips that golfers choose from, selecting the one that feels most comfortable to you is important, and then sticking with it so you don’t have changing variables as you learn.
Single Overlap Grip: (assuming a right handed golfer) The pinky finger on your right hand overlaps with the index fnger on your left hand. The opposite is true for left handed golfers.
Interlock Grip: The same layout as the single finger overlap grip, except that the pinky on your right hand (for righty’s left hand for lefties) interlocks with the index finger on the opposite hand.
Baseball Grip: Probably not a difficult one to imagine, basically you’re grippping the club shaft like a base ball bat. Without any overlapping or interlocking of fingers. All ten fingers should be touching the grip on the club shaft.
Any one of the grips described above will work well, the key as mentioned is to choose the one that feels right...
