Airbending shinobi masters employ training exercises to aid their students in mastering the bending art. Training in airbending techniques focus on avoiding resistance. According to Jiraiya, one requires a quiet environment free of distractions to accomplish this.
Because airbending is the most defensive of all nature elements, a shinobi or a monk need to build up the instinct in order to avoid and evade conflict unless absolutely necessary. To accomplish this, the airbending gates are used. Airbending currents are used to set the gates in motion, either by a sensei or a genin or monk-in-training. The goal is to maneuver through all the gates without touching them; failure to do so results in the student having to restart the test. The genin is required to learn how to switch the directions at the moment of notice to get to the other side.
Because shinobi move like the wind, airbenders focus even more on evasion, as per the Air Nomad philosophy of avoiding violence. This leads the airbending training to focus on evasive capabilities more than offensive ones. A usual monk obstacle course for training consists of suspended sand bags to avoid, a rope to cross, balancing points to navigate, and a large rock wall to climb, much like Konoha's cliff climbing practice.
Air is the element of freedom, and so it is necessary for its practitioners who seek to master it to get a mindset of freedom. Medidation is meant to allow the pupil or their spirit to wander, much like the air. It is supposed to be simple, with no chance of failure. Tree climbing training allow the pupil to keep warmth and gain breath and blood control.
