Physical activity terminology

Some activity is better than none, and more, up to a point is better than less. So if you are physically active, meaning that you perform bodily skeletal muscle movement that results in a substantial increase in your energy expenditure, you gain greater health over being totally inactive. The greatest gains are seen with regular exercise of at least 30 minutes per day.
Exercise is a type of physical activity that is planned, and structured so that repetitive bodily movements are made to improve one or more components of fitness.
Health related fitness is characterized by five components, cadiovascular endurance, muscular strength and endurance, body fat and flexibility.
Skill related physical fitness would imply agility, coordination, power, balance and reaction time.
Additionally, it is important to clearly understand the wide range of intensities associated with physical fitness. More on this in a later post.

Participant / observer the best way to learn

Trying to intergrate a new behavior? Start observing the new behavior in others around you and in yourself. Use others as a rebounding tool. Do you like how a behavior looks on someone else?
Ask them how they came about this behavior? Ask yourself how it feels to wear this behavior? What about this behavior makes you feel energized, in control, or valued by yourself and others? Look Listen, and Feel the new behavior and it will become you.
