There is a buffer between real violence and training and there has to be one to allow progress both mental and physical.
Many martial arts today rely on padded surfaces and body padding. This allows for higher throws in practice and greater force exerted in contact in striking and impact.
There is however also negative in this sport application. It is we do not know how to move our bodies on hard surfaces and most do not know how to strike and get struck with no padding. Bone and flesh.
Give yourself the gift of the hard floor and the wall.
Learn to place your body from standing up to laying down on hard ground first slowly and then with awareness and smoothness it will become faster naturally and you will gain a real world ability.
Stand in front of a wall ( A good one. Many crumble) and place your hand and then fist on it. Learn to push first and to sink second and allow the entire body to become one.
There is no limit except what we place on ourselves and hard contact allow us to open new awareness and ability inside us.
Start slow and start now.
