Physical Fitness- We decline to offer a simple definition of physical fitness. Instead, it is developed by the following chart:

Physiological	Health related	Skill related	Sports

A comprehensive fitness program tailored to an individual typically focuses on one or more specific skills, and on age or health-related needs such as bone health. Many sources also cite mental, social and emotional health as an important part of overall fitness. This is often presented in textbooks as a triangle made up of three points, which represent physical, emotional, and mental fitness. Physical fitness can also prevent or treat many chronic health conditions brought on by unhealthy lifestyle or aging. Working out can also help people sleep better. To stay healthy it is important to engage in physical activity.

The U.S. Centers for Disease Control and Prevention encourages the adult public, ages 18 to 64, to engage each week in at least one and a quarter hours of vigorous-intensity aerobic activity or two and a half hours of moderate-intensity aerobic activity; that time can be met in any increments.

Diet is an important component to overall health that works best in combination with exercise.
