Ninja training refers to the practice and development of skills associated with the historical Ninja, or Shinobi, who were covert agents in feudal Japan. This training often includes physical conditioning, martial arts, stealth techniques, and the use of various weapons. The goal is to enhance agility, strength, and mental focus, enabling practitioners to perform tasks with precision and efficiency. In modern contexts, ninja training can be found in various forms, such as martial arts classes, obstacle courses, and fitness programs. These activities aim to promote physical fitness, discipline, and self-defense skills while drawing inspiration from the legendary abilities of the Ninja.
