Weight training
Exercise is any bodily activity that enhances or maintains physical fitness and overall health and
wellness.[1]
It is performed for various reasons, to aid growth and improve strength, preventing aging,
developing muscles and the cardiovascular system, honing athletic skills, weight loss or
maintenance, improving health[2] and also for enjoyment. Many individuals choose to exercise
outdoors where they can congregate in groups, socialize, and enhance well-being.[3]
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.[4]
Classification
An aerobics exercise instructor in USA motivates her class to keep up the pace.
Physical exercises are generally grouped into three types, depending on the overall effect they
have on the human body:[5]
Aerobic exercise is any physical activity that uses large muscle groups and causes the
body to use more oxygen than it would while resting.[5] The goal of aerobic exercise is to
increase cardiovascular endurance.[6] Examples of aerobic exercise
include running, cycling, swimming, brisk walking, skipping rope, rowing, hiking, dancing,
playing tennis, continuous training, and long distance running.[5]
Anaerobic exercise, which includes strength and resistance training, can firm, strengthen,
and increase muscle mass, as well as improve bone density, balance, and coordination.
[5]
Examples of strength exercises are push-ups, pull-ups, lunges, squats, bench press.
Anaerobic exercise also includes weight training, functional training, eccentric training, interval
training, sprinting, and high-intensity interval training which increase short-term muscle
strength.[5][7]
Flexibility exercises stretch and lengthen muscles.[5] Activities such as stretching help to
improve joint flexibility and keep muscles limber.[5] The goal is to improve the range of
motion which can reduce the chance of injury.[5][8]
Physical exercise can also include training that focuses on accuracy, agility, power, and speed.[9]
Types of exercise can also be classified as dynamic or static. 'Dynamic' exercises such as steady
running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the
improved blood flow. Conversely, static exercise (such as weight-lifting) can cause
the systolic pressure to rise significantly, albeit transiently, during the performance of the exercise.
