Aerobic exercise
Aerobic, or cardiovascular, exercise is particularly important in the prevention of coronary heart disease. This is any kind of activity that increases your breathing rate and gets you breathing more deeply. These activities include walking, running, swimming, dancing or any of the aerobic (cardiovascular) machines at the gym, such as the rowing machine, treadmill, stepper or elliptical trainer.
These are designed to increase the strength of your heart muscle by improving your body's ability to extract oxygen from the blood and transport it to the rest of the body. Aerobic exercise also enhances your body's ability to use oxygen efficiently and to burn (or metabolise) fats and carbohydrates for energy.
