Physical fitness is the result of regular physical activity, proper diet and nutrition, and proper rest for physical recovery within the parameters allowed by the genome.

Physical fitness is often divided into the following types (in alphabetical order):

Agility
Balance
Body Composition
Cardiovascular endurance
Coordination
Flexibility
Muscular strength & endurance
Speed
Many sources also cite mental and emotional health as an important part of overall fitness. This is often presented in textbooks as a triangle made up of three sub-sections which represent physical, emotional, and mental fitness. Hence, one may be physically fit but may still suffer from a mental illness or have emotional problems. The "ideal triangle" is balanced in all areas.

Specific or task-oriented fitness is a person's ability to perform in a specific activity with a reasonable efficiency, for example, sports or military service. Specific training prepares athletes to perform well in their sports.

Examples are:

100m sprint - in a sprint the athlete must be trained to work anaerobically throughout the race.
Marathon - in this case the athlete must be trained to work aerobically and their endurance must be built-up to a maximum.
Fitness testing is also conducted for fire fighters and police officers to determine if they are capable of the physically demanding tasks required for the job before they are employed.
