An effective and healthy workout has several components, including a warm-up, some stretching, cardio training, resistance training, and a cool-down.
Categories of Exercise
All exercise can be categorized as either aerobic (meaning with oxygen) or anaerobic (without oxygen).
Aerobic training refers to a type of longer-term energy use in the body that requires the presence of oxygen molecules. Examples include jogging, walking, moderate bike-riding, and aerobics classes (now you know where the name came from). Aerobic exercise also activates your immune system, helps your heart pump blood more efficiently, and increases your stamina over time.
