Firefighting is a physically demanding occupation placing great stress on the muscular-skeletal system eg joints, muscles, tendons and on the heart and lungs. The firefighter must also have good co-ordination and balance with the capability to respond quickly and effectively in emergency situations, demonstrating a continuous high level of fitness.

To ensure a near maximal response from heart and lungs, regular (at least 3 times weekly) exercise of at least 30 minutes duration should be undertaken which will increase the heart rate measured by a pulse rate of 180-190 beats per minute. Failure to demonstrate the correct aerobic capacity will automatically terminate the application.

Those people who do not regularly take any form of exercise should commence a fitness programme and slowly and gradually increase the intensity and duration of the chosen form of exercise over a period of several weeks.
