Unfortunately there is no way to change your genetics. The way your body is layed out cannot be changed for the most part as far as structure. If we could, everyone would be 5'8" or taller, etc... But what you can do is change the strength of your hands. Because you could have very big hands, but they could be weak. Instead of trying to be like other people. Look at yourself and see what needs to be improved. And base your results on what you use to be like other than how you compare to someone else.
