Golf Swings have many moving parts, but without a solid base the whole process falls apart. Maintaining your balance is what generates a consistent swing and impact position, this also creates a more efficient motion and you can deliver the clubhead to the ball with both speed and accuracy. Loss of balance effects tempo, rhythm, and creates a motion with energy loss.
An advanced player can swing each club in their bag with the same consistent tempo because they’re muscle memory is advanced with a reputable motion of legs and core muscles. An amateur player tends to swing out of their natural tempo (too fast) having an immediate effect on balance and any chance for solid contact.
To find the correct balance, it’s essential to know where your weight should be during the swing. Following are three balance checkpoints during the swing, as well as drills to help you feel the correct balance and more solid shots.
ADDRESS
At address, your weight should be balanced equally over the insteps of both feet (on the balls of your feet) . This puts you in an athletic, ready position..

***If your weight falls on your toes, the clubhead will tend to start outside the target line.
If your weight rests on your heels, the path will tend to be too inside.
TOP OF SWING
As your upper body coils, about 90 percent of your weight shifts over the trail foot side. It’s imperative to maintain a good right knee flex. Many golfers lose their balance because of tension in their legs.
At the top of the backswing, your balance point is over the middle of your right foot.
FINISH
On the follow-through, the swing’s momentum should carry you to a full, balanced position, with majority of your weight on your lead foot. If you’re stumbling at the finish, chances are your rhythm and timing are off, and the shot less than satisfying.
