What is the lever system in golf?

The lever system in golf primarily refers to the connection and relationship between the arms and the body during the golf swing. This concept is crucial because it aids in creating a coordinated movement whereby the shoulders, arms, and club work together effectively.

When the arms hinge and unhinge properly through the swing, they act like levers, allowing for an efficient transfer of energy from the golfer's body into the club. This connection helps to maintain control over the clubface and ensures that the swing path is consistent, ultimately leading to improved accuracy and distance. Understanding the lever system helps golfers improve their mechanics, leading to a more effective and powerful swing.

The other options, while important in different contexts, do not define the lever system specifically. The speed of the clubhead at impact is a result of the swing mechanics rather than the lever system itself. The grip technique is essential for control but doesn't pertain directly to the leverage of the swing. Lastly, the type of equipment used for practice is a separate consideration that does not involve the biomechanical aspects of the swing.
