Aerobic exercise also known as "cardio"- is when oxygenated blood is pumped by the heart to muscles in the body. The term aerobic actually means "with oxygen," which means that breathing controls the amount of oxygen that can make it to the muscles to help them burn fuel and move. You can increase your endurance on and off the golf course by doing bouts of "cardio" exercise.
The American Heart Association recommends that everyone reach a minimum of 30 minutes of some form of cardiovascular exercise 5 to 7 days per week.
