Please remember that all joint action is possible because the muscles above and below the joint of 'concern' cross the joint in question and enable the function of both extension and flexion. It is a very precarious process to dissern the exact origin of the problem or advantage. Certainly some people are born with the advantage of certain muscular developments. (i.e. many runners I have known that are renowned in their distance and still have skinny calves yet a guy in the streets has 'great' chisled calves. ) The forearms are a secondary muscle, though, important in the fulfillment of the golf swing. Development is often not as much a reflection of function but more a reflection of genetics. Size is not, and I repeat NOT, a reflection of power or function. There's more I could say . . . but it's more fun if someone else has more input. Vik
