Matt Baker (Malaska Certified Coach) explains how the 'Lever System' generates effortless speed by utilizing proper wrist hinge. He demonstrates a split-grip drill designed to help golfers stop over-controlling the club and instead leverage the natural unhinging and re-hinging process that accounts for 84% of clubhead speed.
Approximately 84% of clubhead speed is generated by the wrists, not physical effort.
The Lever System requires a specific sequence: hinge in the backswing, unhinge in the downswing, and re-hinge through the strike.
Trying to control the club by removing wrist action is the primary cause of a 'weak' feeling swing.
Use the split-grip drill to feel the club's natural momentum rather than forcing power.
