Fitness
the ability to carry out daily tasks with vigor and alertness, without undue fatigue, and with ample energy to enjoy leisure-item pursuit and meet unforeseen emergencies
Health-Related Physical Fitness Components
Cardiorespiratory endurance, body composition, muscular strength, muscular endurance, flexibility
Cardiorespiratory endurance

Body composition
the relative amounts of muscle, fat, bone, and other vital parts of the body
Muscular strength
the ability of muscle to exert force
Muscular endurance
the ability of muscle to continue to perform without fatigue
Flexibility
the range of motion available at a joint
Skill-related Physical Fitness Components
Agility, coordination, balance, power, reaction time, speed
Agility
the ability to change the position of the body in space with speed and accuracy
Coordination
the ability to use the senses, such as sight and hearing, together with body parts in performing tasks smoothly and accurately
Balance
the maintenance of equilibrium white stationary or moving
Power
the ability or rate at which one can perform work
Reaction time
the time elapsed between stimulation and the beginning of the reaction to it
Speed
