What is Fitness? “Physical Fitness” Microsoft Encarta Reference Library 2004: “the ability of the human body to function with vigor and alertness, without undue fatigue, and with ample energy to engage in leisure activities, and to meet physical stresses.”
Fitness is not about being thin, having a small waist, or having bulging muscles. It is a combination of qualities that enable us to be at our full potential in performing vigorous physical activities.
Physical Fitness involves the performance of the heart, lungs, and the muscles of the body. Specifically, it takes into account our Cardio Respiratory Endurance, Muscular Strength, Muscular Endurance, and Flexibility.
To some extent, Fitness also influences our mental and emotional development since what we do with our bodies also affects what we can do with our minds.
Although Physical Fitness and good health influences each other, they are not the same. Healthy people could be physically unfit due to lack of exercise.
On the other hand, Physically Fit people perform their everyday tasks effortlessly.
