A golf practice and exercise device has an elevated arm from which an impact object is suspended for swinging movement. The object is positioned with a clubhead impact target in position for striking by the clubhead of a golf club swung by a golfer. The resistance to the impact of the golf club is adjustable. A sensor detects the magnitude and velocity of the striking force, and a display displays an indication as to how far a golf ball would have gone after being struck with a force and velocity of the detected magnitude.
