We are always reminded that exercise could do wonders for the body. Aerobics, a kind of exercise which helps your body use more oxygen while maintaining your target heart range, can definitely help a person live longer and healthier. There are studies showing that 30 minutes of aerobics every day would benefit the body a lot. Performing regular aerobic exercises would gradually make the heart larger. A bigger and larger heart would be able to provide more oxygenated blood which can be used by the muscles. This could also mean more energy whether for longer or shorter periods of exercise or physical activities.
