Three-time Major champion Padraig Harrington explains that 'intention' is the most critical factor in gaining clubhead speed. He demonstrates how to use feedback from launch monitors and specific drills, such as the lead heel lift and step drill, to increase range of motion and master ground forces. This lesson focuses on raising your personal speed ceiling during practice so your on-course swing feels more effortless and controlled.
You must have the active intention to hit the ball harder; strength and flexibility won't transfer without it.
Use a launch monitor to get objective feedback and give yourself a number to beat during speed sessions.
Lifting the lead heel in the backswing is a simple way to increase your swing arc and gain a few extra miles per hour.
Sequence your ground forces by starting the 'step' toward the target before the backswing is even finished.
Practice at 'full tilt' several times a week to keep your maximum speed ceiling from dropping.
