"Fitness" is a broad term that means something different to
each person, but it refers to your own optimal health and overall
well-being. Being fit not only means physical health, but emotional and
mental health, too. It defines every aspect of your health. Smart eating
and active living are fundamental to fitness.
According to the Academy of Nutrition and Dietetics' Complete Food and
Nutrition Guide (3rd ed.),
When you are fit, you have:
1. Aerobic exercise
Jogging is a form of trotting or running at a slow or
leisurely pace. The main intention is to increase physical
fitness with less stress on the body than from faster running
but more than walking, or to maintain a steady speed for longer
periods of time.
Walking is one of the most popular forms of exercise
worldwide. It doesn't require expensive equipment or special
skills, and it provides a wide range of health benefits.
A treadmill is a piece of equipment, for example an
exercise machine, consisting of a wheel with steps around its
edge or a continuous moving belt.
Swimming is an individual or team racing sport that
requires the use of one's entire body to move through
water.
Cycling can help to protect you from serious diseases
such as stroke, heart attack, some cancers, depression,
diabetes, obesity and arthritis.
2. Anaerobic exercise
Weight training is a common type of strength training
for developing the strength and size of skeletal muscles. It
uses the force of gravity in the form of weighted bars,
dumbbells or weight stacks in order to oppose the force
generated by muscle through concentric or eccentric
contraction.
An isometric exercise is a form of exercise involving
the static contraction of a muscle without any visible movement
in the angle of the joint.
Sprinting is running over a short distance at the
top-most speed of the body in a limited period of time. It is
used in many sports that incorporate running, typically as a way
of quickly reaching a target or goal, or avoiding or catching an
opponent.
Interval training is a type of training exercise that
involves a series of high-intensity workouts interspersed with
rest or relief periods. The high-intensity periods are typically
at or close to anaerobic exercise, while the recovery periods
involve activity of lower intensity.
