Agility, balance, and coordination each refer to different fitness skills. Agility refers to the ability of executing rapid changes in any direction. Balance refers to the ability of moving while remaining upright. These two skills are related, but still distinct. Dodging back-and-forth in a sports game is an example of good agility, while moving around without slipping or falling is an example of good balance. Coordination, meanwhile, is the ability of using different body parts together in concert. An example of coordination is running down the length of a football field while passing the ball to another player.
