Clubs not suited to the player will not perform correctly and over time become damaged due to the stresses and strains caused by a poor fitting!
Golf club manufacturers generally supply retail stores with clubs that are set up with lies, shaft length, grip size and swing weight to suit players of a medium build.
Many players, especially beginners, all too often buy golf clubs straight off the shelf of the local golf store without taking into account whether they are suited to their size and build.
