We can break the movements of the backswing down into a sequence of five - the clubhead moves away first followed by the hands, the shoulders, the hips and finally the feet. The downswing sequence of movement is exactly the opposite. The first movement is initiated by the feet followed by the hips, the shoulders, the hands and finally the clubhead. To have good rhythm in your golf swing this sequence should be repeated for every swing. Problems creep into our swing when for example we start the downswing with our shoulders and hands first.
Balance is when there is bodily equilibrium or stability.
Balance in a golf swing must start at address. This causes the ball to start out to the left of the target and for the majority of golfers this is usually accompanied with a slice. Conversely, if the golfer were out of balance with the weight too much toward their heels the tendency would be for the swing to come too much from the inside to outside that would create a push - a ball starting out to the right. The position in the golf swing that is most telling if a player is in balance or out of balance is the finish. If you can not hold your finished position at the conclusion of each swing consistently, then you most likely will find yourself hitting errant shots throughout your round.
