There are really six basic golf swing fundamentals that need to be learned and managed whether you’re a beginner or a pro.
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 to change variables as you learn.
Single Overlap Grip: (assuming a right-handed golfer) The pinky finger on your right-hand overlaps with the index finger on your left hand. The opposite is true for left-handed golfers.
Anyone of the grips described above will work well, the key as mentioned is to choose the one that feels right for you and practice using that one.
Posture and Mechanics
How you set the ball in your stance, the flex at your knee, straightening of the back, hip bend, and angle which you maintain through the whole swing. The width of your stance should be approximately shoulder width. Knees should be kept slightly bent to allow some motions, and your back kept straight at about an 80-degree angle.
Be sure you’re bending at the hips and not your back, keep your back straight at all times. The angle that your back maintains when you’re coming through your follow-through should be the same which you started within your backswing. If you change/move the angle of your back then everything else in your swing mechanics will also change.
Managing how your body swings through from your head to your toes and turning into your swing with your hips is the pivot.
Hands and Arms
Hand and arm relationship or better known as coordination is a very important step to learning the golf swing fundamentals.
Picking out a Target
Where do you want the ball to go? Alignment is an important part of the swing that not everyone pays attention to. If you’re aiming for the green, then you should make sure that is where your body is aimed and where it will be facing once you’ve followed through with your swing.
Of course, there is a mental aspect to choosing a target as well. If there is a sand or water hazard directly in front of you chances are guess where your ball is going to land. Either at the beach or for a swim in that water hazard. Focus on something ahead, keep your main objective in mind, and ignore hazards treat them as if they’re not there.
Probably the most important yet the least physical aspect of golf swing fundamentals. Some pros say that up to 90% of their game is mental, you have to be able to get in the right state of mind, visualize the next shot, and also perform all the above-mentioned fundamentals without thinking about them. So practice is what it takes to get them down. Your body will be able to reach a point where it’s all-natural, and you won’t have to think about the next step, until then keep practicing.
