There are ten recognised general physical skills. They are cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy. You are as fit as you are competent in each of these ten skills. A regimen develops fitness to the extent that it improves each of these ten skills.
Cardiovascular/Respiratory Endurance – The ability of body systems to gather, process, and deliver oxygen.
Stamina – The ability of body systems to process, deliver, store, and utilize energy.
Strength – The ability of a muscular unit, or combination of muscular units, to apply force.
Flexibility – the ability to maximize the range of motion at a given joint.
Power – The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.
Speed – The ability to minimize the time cycle of a repeated movement.
Coordination – The ability to combine several distinct movement patterns into a singular distinct movement.
Agility – The ability to minimize transition time from one movement pattern to another.
Balance – The ability to control the placement of the bodies center of gravity in relation to its support base.
Accuracy – The ability to control movement in a given direction or at a given intensity
