Having a consistent and solid golf swing is the key to a good game. Good swings are built largely on balance. If you find that you move backwards or forwards on your feet while swinging, you are likely throwing off the entire process. Even if the rest of your technique is good, poor balance will ruin the swing. Practice swings while balancing in a difficult place, like in a narrow area or on a piece of foam. This will help you stay balanced when fully on the ground.
Another fundamental swing error is not using the hands and body together. Power comes from your body, so focusing on just your hands results in weak shots. Additionally, using your body is important for maintaining control over the club and swinging consistently. Still, don’t completely forget about your hands. Instead of raising them over your head when finishing a swing, keep them lower, by your shoulders. This improves the trajectory of your shots.
Finally, check the speed at which you swing. It’s very difficult to swing slowly, but swinging too quickly is often a problem, because it prevents your body from properly shifting its weight and getting in line. Correcting the speed puts more power behind your swings and promotes consistency. Stay relaxed while going through the motions of a swing.
