Sometimes I just need to scream or throw something or hit something. A little bin of stuffed animals is a good choice to throw. Kicking a soccer ball. Hitting golf balls or baseballs at a batting cage can help. Punching a pillow. A punching bag is awesome and a good workout. You can tear paper into shreds. You can squeeze putty or playdoh. Sit in your car and scream. Scream into a pillow.

The techniques everyone gave are great as well. I just find that sometimes fighting it just stuffs it down. Letting it come up and out in a non-violent way is better for me. Breathing and other techniques help me more when I use them to calm after I let the rage flow for a bit.
