When I was struggling with rage and anger I hooked up with a friend who boxed. He taught me the basics and would spar with me. It was great fun to learn specially being a girl and it was an incredible way to relieve and release the rage and anger. Other things I did was hit a pillow and shout and scream, I'd go somewhere secluded and just scream my head off, even sitting in the car I would do it. But, I have to say that the boxing, running and journalling have really worked the best for me in terms of managing and releasing anger.
