Exercise is any bodily activity that enhances or maintains physical
fitness and overall health and wellness. It is performed for various
reasons, to aid growth and improve strength, develop muscles and the
cardiovascular system, hone athletic skills, weight loss or maintenance,
improve health, or simply for enjoyment. Many individuals choose to
exercise outdoors where they can congregate in groups, socialize, and
improve well-being as well as mental health. In terms of health
benefits, the amount of recommended exercise depends upon the goal, the
type of exercise, and the age of the person. Even doing a small amount
of exercise is healthier than doing none.
