Human beings all have the same mechanical structure regardless of size, strength, age, or gender. The hinging points or axis are the same for everyone as well as skeletal, tendon, joint, and muscle function. This is why exercise machines at a health club can be used by anyone and produce the same results. The only adjustment necessary in these machines is for the length of the arms, legs, etc. of the individual. By the same token all golf clubs should be built to the same specifications with the only adjustment being made to the length of the golf club in relation to the optimum lie angle.  It is true that the stronger golfer will achieve greater distance than the weaker golfer and is the reason why golf courses offer varying tee box locations. This is just a function of individual strength that produces a greater swing force with a higher swing speed, but it does not alter the sound mechanical principles of a well designed golf club. For instance, those golfers with a very low swing speed should substitute #5 and #7 woods for the #3 and #4 irons. The specifications of the golf clubs, however, should never be altered based on the strength of the golfer. A mechanically perfect golf club design is mechanically perfect for everyone regardless of strength, size, age, or gender. 1 Iron Golf clubs are being played and enjoyed by men and women in every age and strength category world-wide.
