lifestyles physical fitness is now considered

Around 1950, perhaps consistent
with the Industrial
Revolution and the treatise of World
War II, the term “fitness”
increased in western vernacular by a
factor of ten. Modern definition of fitness
describe either a person or machine’s ability to perform
a specific function or a holistic definition
of human adaptability
to cope with various situations.
This has led to an interrelation
of human fitness and attractiveness
which has mobilized global
fitness and fitness equipment industries.
Regarding specific
function, fitness is attributed to personnel
who possess significant
aerobic or anaerobic ability,
strength or endurance.
A holistic definition of fitness is
described by Greg Glassman
in the CrossFit journal as an increased
work capacity across
broad times and modal domains; mastery of several attributes
of fitness including strength, endurance,
power, speed, balance and
coordination and being able to improve
the amount of work done
in a given time with any of these domains.
A well rounded
fitness program will improve a person in
all aspects of fitness,
rather than one, such as only cardio respiratory
endurance or only weight training.

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 some
people sleep better and possibly
alleviate some mood disorders in
certain individuals.

Developing research has demonstrated
that many of the benefits
of exercise are mediated through the
role of skeletal muscle as
an endocrine organ. That is, contracting
muscles release multiple
substances known as myokines
which promote the growth of
new tissue, tissue repair, and various
anti-inflammatory functions,
which in turn reduce the risk of developing
various inflammatory diseases.
