Aerobic exercise gets the heart working to pump blood through the heart more quickly and with more force than normal. As blood is pumped faster, it must be oxygenated more quickly, which quickens respiration. Aerobic exercise strengthens the heart and boosts healthy cholesterol levels. Low impact aerobics include walking and swimming. Running, tennis and dance are high impact aerobics.
