Agility or nimbleness is an ability to change the body's position quickly and requires the integration of isolated movement skills using a combination of balance, coordination, speed, reflexes, strength, and endurance. More specifically, it is dependent on these six skills:

• Balance – The ability to maintain equilibrium when stationary or moving through the coordinated actions of our sensory functions ;
• Static balance – The ability to retain the center of mass above the base of support in a stationary position;
• Dynamic balance – The ability to maintain balance with body movement; an equal distribution of weight;
• Speed – The ability to move all or part of the body quickly;
• Strength – The ability of a muscle or muscle group to overcome a resistance; and lastly,
• Coordination – The ability to control the movement of the body in co-operation with the body's sensory functions.
