In some fanfictions, Anko might train Naruto by focusing on his stealth skills. She could take him to various terrains and teach him how to move without being detected. For example, in the forest, she shows him how to step quietly on different types of ground and use the foliage to his advantage.
Another aspect of Anko's training could be mental preparation. The Chunin Exams are not just about physical strength. Anko could put Naruto through tough mental challenges, like solving complex puzzles or facing his fears in simulated scenarios. This would help him stay calm and think clearly during the actual exams.
