Swing through, not to, the ball
Most slow-swinging amateurs slap at the ball or try to scoop it up into the air, which causes the clubhead to slow down through impact. There's no gradual buildup of speed, which is a defining trait of good tempo. To learn how to accelerate the club through impact to a full, balanced finish, practice swinging with your headcover on your driver. The additional resistance on the clubhead will force you to drive it through impact into a full finish, and will teach you how to use tempo to generate more speed and power.--Karen Palacios-Jansen, one of Golf Digest's 50 Best Women Teachers in America
