form refinement training
In martial arts, practice focused on perfecting the form (kata) rather than free sparring or application.
Every morning, we do form refinement training for an hour at the dojo.
By repeatedly practicing form refinement, you internalize the fundamental movements.
形 means 'form' or 'kata' in martial arts; 形稽古 is the training that focuses on that form.
Compound of 形 (kata, 'form') and 稽古 (keiko, 'practice, training'). The term is specific to martial arts contexts.
