My wrist are thin as compared to my body.. feels awkard when been with people around. any suggestion to increace the diameter of wrist?

Let's talk: Wrists aren't covered with muscle and their diameter is a function of your bone structure, which you cannot change. Many (most?) women prefer a lighter-framed man. Tobey maguire and brad pitt are celebrities with slender wrists. To build forearms, put a weight on a string and use your hands to wind it up around a rod. Get fit and the wrists won't be a problem.
