While Experience Points (XP) are required to Level Up Trainers, Prestige is needed to Level Up Gyms.
Prestige can be earned by defeating Pokémon in battle at friendly Gyms (also known as Training).
When a Gym gains enough Prestige it will Level Up and gain an additional defensive Pokémon slot. Teams will want to work together and Train at Gyms to earn Prestige quickly in order to build up Gym defenses.
