Fitness & Exercise

Physical exercise is defined as the ability to perform regular moderate to vigorous physical activity without great fatigue. It is activity performed in order to develop or maintain physical fitness and overall health. Frequent and regular exercise is an important component in the prevention of some of the diseases of affluence such as cancer, heart disease, cardiovascular disease, diabetes and obesity.

Exercises are generally grouped into three types depending on the overall effect they have on the human body:

• Flexibility exercises such as stretching improve the range of motion of muscles and joints.

• Aerobic exercises such as walking and running focus on increasing cardiovascular endurance.

• Anaerobic exercises such as weightlifting increase short-term muscle strength.
