What is Aerobics? The word aerobics comes from Greek word: aero, meaning “air.” It 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 (flexibility, muscular strength, and cardio-vascular fitness).

Formal aerobics classes are divided into different levels of intensity and complexity. Aerobics classes may allow participants to select their level of participation according to their fitness level. Each class is designed for a certain level of experience and taught by a certified instructor with a specialty area related to their particular class.

During aerobic exercise, you repeatedly move large muscles in your arms, legs and hips. Aerobic fitness, also called cardiovascular fitness, refers to the ability of your heart, blood vessels and lungs (cardiovascular system) to supply fuel during sustained physical activity.

Aerobic activities include: walking, jogging, jumping, biking, climbing, rowing, swimming, cycling and skiing. Dancing is also an aerobic exercise.

When you’re aerobically fit, your body more efficiently takes in and uses oxygen to sustain movement more efficiently. To sustain repetitive muscle movement, your body takes in more oxygen. You breathe faster and more deeply to maximize the amount of oxygen in your blood stream. You heart pumps blood faster and more forcefully. The force of each beat of your heart increases to maximize blood flow to your muscles and back to your lungs. To get more oxygen to your muscles, small blood vessels (capillaries) dilate and carry away waste products, such as carbon dioxide and lactic acid. Over time, more capillaries will actually develop in the muscle to provide for more efficient oxygen delivery and waste removal.

Regular aerobic exercise releases endorphins, your body’s natural painkillers. Taking part in regularly scheduled aerobic exercise can help you prevent certain diseases and manage others. It can also help you feel better.

Aerobic exercise can help reduce your risk of coronary artery disease and developing hypertension (high blood pressure). Exercise improves your blood fats. It increases the concentration of high-density lipoprotein (HDL) cholesterol (the “good” cholesterol) and decreases the concentration of low-density lipoprotein (LDL) cholesterol (the “bad” cholesterol) in your blood. Improving blood fats results in less build-up of plaques in your arteries. Deposits of plaques in blood vessels leading to your brain can result in a stroke.

Aerobic exercise helps you control your weight, reducing the likelihood of your being overweight or obese. It also helps activate your immune system and prepare it to fight off infection. People who exercise regularly are less susceptible to minor viral illnesses, such as colds and flu.

Burning fat and moving and to your favorite music, you will be in excellent mood while genial and emotional atmosphere will become an extra stimulus. With a creative instructor, you will not enjoy this class and will be filled with desire to move again and again…
