Jinki is a Japanese term you hear a lot at the Kodokan. After bowing in, training sessions often begin with a short reminder of “Jinki” and the importance of giving the training your maximum effort. The instructors will explain how it is acceptable to be thrown or beaten in randori if you are giving your maximum effort. But it is not acceptable to be beaten if you were not giving your maximum effort.
Then at the end of each training session, the instructor will thank the class for their effort, and remind them that they should be prepared to give the same effort at the following day’s training.
