Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness such as flexibility, muscular strength, and cardiovascular fitness. It is usually performed to music and may be practiced in a group setting led by an instructor, although it can be done solo and without musical accompaniment. Aerobics classes are divided into different levels of intensity and complexity and will have five components: warm-up, cardiovascular conditioning, muscular strength and conditioning, cool-down, and stretching and flexibility.
Aerobic exercise is any type of cardiovascular conditioning, or “cardio” that uses your body’s large muscle groups, is rhythmic and repetitive. It increases your heart rate and how much oxygen your body uses. Examples of aerobic exercises include walking, cycling, and swimming. Aerobic exercise helps keep your heart, lungs, and circulatory system healthy. Aerobic exercise differs from anaerobic exercise, such as weightlifting or sprinting, which involves quick bursts of energy and is performed at maximum effort for a short time.
Aerobic exercise is recommended for reducing the risk of health issues, and 2.5 hours of moderate-intensity aerobic exercise per week is recommended. Even doing an hour and a quarter (11 minutes/day) of exercise can reduce the risk of early death, cardiovascular disease, stroke, and cancer. During aerobic exercise, your blood pumps quickly throughout your body and your lungs take in more oxygen. The word aerobic means “with oxygen,” meaning that your breathing determines the amount of oxygen that gets to your muscles. Oxygen in your muscles is what helps them to move, giving you the strength to exercise.
