What Can you control with chakra?

You have to focus all of you're stamina and energy of you're body into any part of you're body.For exampler - into you're arm,to punch harder.To you're legs - to jump higher,run faster,kick harder . In other Words - chakra is a humans body and soul energy,if you can manipulate both of them together by fusing them,then you're one of a kind. BUT HOW can i transfer chakra? do i just by focusing stuff in to my fist so can destroy in bloody knuckles...-_- or do i need to do some thing else....
