Good morning! If anyone wants to hit their driver farther, it is extremely important to get fit for the driver that will warrant better performance numbers.
Secondly, do something to increase your flexibility. I personally have a stretching routine I follow every day before leaving my house.
Lastly, if you seek more distance with the driver, the club head must go faster! Get in better physical shape and watch your distance increase! The number 1 thing to focus on is your timing, it will change because of increased speed. Take notice of your tempo when you hit the ball far and try to duplicate that rhythm each time. You will hit the ball farther! That’s the secret to increased distance! Good luck!
