When Naruto takes off his weights in fanfiction, it could completely revolutionize his training. He might find that he can now train with stronger opponents, like the elite jounin or even the Hokage. This would expose him to different fighting styles and strategies, which in turn would help him grow as a ninja. Also, his physical training could now include more acrobatic and aerial maneuvers that were previously difficult with the weights on. His chakra control might also be affected, as the change in his body's movement could require different levels of chakra distribution. This could lead to him exploring new ways of using his chakra in combat and non - combat situations.
