Increasing your Distance

Every golfer wants to hit the ball farther.  The first step is you must hit it solid.  The longest shots are the ones hit in the center of the clubface.  The more times you hit the ball in the center of the clubface the more confident you become.  As you become confident, you're able to swing the club faster without concern of the result.  Just a few mph more can make a difference.  As a general rule every mph, plus or minus, equates to 2.5 to 3 yards.
Below is an instructional video from my youtube channel, timcusickgolf, that outlines hitting the ball farther.
