Shadow kick boxing in super slow motion, 60 seconds, 30 for the hit and 30 for the return, or as applicable. One round as relaxed as possible, another as tense as possible, alternating which starts with each workout.
Maximally tensing your whole body to absorb blows better.
Golden Bell/Iron Body training: hard taps to the body in various areas until you can hit yourself as hard as you can completely relaxed without injury or pain, until others can slam on you without injury, until people can stab you and it does nothing when you're tensing, until people can stab you when you're relaxing and it does nothing (knife breaks).
Becoming retarded from getting hit in the head is legitimate, but is also a sign you're lacking neuroplasticity. Boost neuroplasticity by breaking habits continuously. This can be by studying the occult (wizard here) which really is a mind fuck that limbers the entire biological system; even the light stuff like elements (hermetics, traditional chinese medicine, etc) and thought force (william atkinson has some good stuff) can really boost neuroplasticity, learning capacity, wisdom and intelligence.
Other ways are learning how to use the less dominant hand in writing and other motor activities that build ambidexterity. If you notice you can flex or move a certain way on one side but not the other, such as moving a shoulder blade a certain way or muscle activation in the obliques, try to reconcile the difference.
Travel, new experiences, creative activities; writing included!; using your senses in new ways; learn how to live blind, deaf – learn how to taste the air and a million things in food, and smell as well as a dog – learn how to see your body with your eyes closed through the mind's eye so you can move perfectly while blind through an environment or when fighting – etcetera.
And finally, if you're smarter than you ever were by developing the mind through sense and intellect, no one would know that fighting dropped your IQ even 20 point – you could have an 180 IQ and be the smartest man in the room every time, but were dropped there from 200 IQ by fighting.
The gains to spirit and body are worth it though; courage, discipline, daring, resourcefulness – these are worth it.
Do the Iron Head training. Taps to the jaw and noggin' until it's iron.
