The diary entry describes the session’s theme as acquiring a strong posture rather than attacking: holding good posture without forcing it, and letting the minimum muscle required to stay standing handle the rest on its own. The blogger wrote that no matter how relaxed one becomes, the muscles needed to remain upright still work automatically, so there is no need to consciously force the posture.
Posture Over Power in the Seventh Session
The approach built on the previous session, when the practitioner first experienced a relaxed back, which they set out to make the standard. The goal was to stay upright and loose at the same time — good posture achieved without wasted effort, since straining to hold it correctly is itself tiring, the log says.
In practice, the blogger reported that the stronger frame made them surprisingly hard to throw, and their stamina held long enough to complete 12 randori rounds. That compared with two rounds before feeling exhausted in the prior session — progress, the entry notes, though not a complete solution.
The Lingering Problem: Attacking While Relaxed
The same session exposed the next hurdle. The blogger wrote that they still could not attack effectively, because the moment they tried to initiate a technique they tensed up, and moving well while maintaining good posture remained out of reach. The log concludes that this, too, requires training.
Why the Diary Says Posture Carries the Power
The entry argues that posture is decisive in judo: with good posture, the output of the arms and legs rises, while poor posture creates a sensation of using force that is really just tension. The claim, as the blogger puts it, is that a good posture produces more power with less force. The log cites sports science describing an inverse relationship between tension in the extremities and tension in the core, and notes that martial arts have long taught the same principle — a basic concept common to all sports, easy to state and extremely difficult to master.
What Mastery Actually Requires
According to the diary, holding good posture while relaxed demands a minimum underlying strength, and moving the limbs loosely has to become unconscious through repetition. The blogger adds that facing a stronger opponent can trigger tension and freezing, so a calm mind under difficult conditions is also necessary.
The log looks back at traditional training methods used to build this foundation: thousands of straight punches, 1,000 push-ups, repeated shiko stomps, endless footwork drills, and the constant ball touches practiced by soccer and basketball players. As the limbs relax through repetition, the core grows stronger in inverse proportion, the entry says, and the core can be trained directly as well — citing the example of an athlete who could deploy core power immediately. The blogger’s closing thought is that consistent basic training may one day make several skills suddenly click at once, even if they are not there yet.
