For the sake of simplicity, all advice on swings and drills is provided from a right handed perspective; lefties …. well, you know what to do!
A concept of the golf swing that we all need to understand when it comes to clubhead speed, is that it needs to happen at impact.
Most of my new students typically try produce speed early in the swing, at the top of the backswing as they transition into their downswing.This is completely wasted effort, and an inefficient movement.
Don’t try for speed too early in the downswing, rather let the swing unfold sequentially in order to gather speed for impact.
A good drill to feel this is to take one handed swings with an inverted driver, right hand only.
Let your hip slide start the downswing, and keep your right wrist hinged for as long as possible as you rotate through the swing. Let your right hand release through impact, producing a loud swooshing sound right at impact.
Not before, not after. Right at impact.
Maintain your lag by holding your wrist in position longer than normal, then let it snap at impact.
Don’t flip the club, maintain your flying wedge (cupped position) in your right wrist and let it cover an imaginary ball through impact.
Practice this regularly and enjoy the results.
Love your practice, enjoy your golf,
