This Driver video zeroes in on creating speed. PGA professional Davis Love Jr. was one of the best drivers of the golf ball. His father had him do a drill which was phenomenal at creating and increasing speed. By creating more and more speed, everything has to stay in sync when you swing. You won't sync with your swing if you generate more speed and your body moves too fast. Your swing doesn't work, your smash factor comes down, and you hit the ball crooked.
Lay down four balls in sequential order. The object of the drill is to swing at each ball while increasing speed as your move on to the next ball. For the first ball, make a full swing and only hit the ball 125 yards in the air. This appears to be easy but is actually challenging to do. The point is to hit the ball squarely in the center of the clubface. At that speed, there is just enough speed to feel the momentum of the club, feel how your body works, and control the clubface. Golf is about different speeds and being able to sense and control where you are in space in time at different speeds.
Make the same full swing for the second ball but add a little more speed to hit the ball about 155 to 160 yards in the air. To create more speed, push away with your legs creating more force.
Then, move to the third ball and increase your speed to hit the ball 200 yards. If you lose control, back off the speed and make sure your swing is in sync with your body before you try to increase speed.
Going to the last ball, Mike swings at what he refers to as his full play swing, which is swinging at about 75-85% of his swing capacity. Mike doesn't usually swing 100% because it's harder to control the ball.
Go through this drill to help you as you start to increase speed making sure your body is in sync with your swing.
