Understanding the physical make-up of the golf club, its weight distribution and how we control that weight in the golf swing, especially as it relates to the center of mass is very important if you want to be a good striker of the golf ball.
If you can control where that center of mass is during the golf swing, you can control where the clubface is as well. Once you allow that center of mass to get beyond your arms and it starts acting as the pulling mechanism, you’re no longer in control of the clubface, which results in poor and inconsistent shots.
