The Interval Program is among the best for conditioning your cardiovascular system. Each 1-minute interval raises and lowers your level of exertion repeatedly throughout the duration of the program.

When you begin the program, the incline and speed settings are preprogrammed. To change the settings, press the appropriate arrow key and continue. The changes are applied to the remaining intervals. The display lets you know when the incline or speed levels are about to change, and indicates the levels of the next interval.

When you complete the program, any changes made to the incline and speed settings are not saved.

The Fitness Test provides a means of comparing your fitness level with the official fitness test of the International Association of Firefighters (IAFF). It is written using the Gerkin Protocol, which is the basis for the official IAFF fitness test and part of their Wellness and Fitness Initiative.

During the test, the treadmill gradually increases the incline and speed in specific stages. The test ends when you surpass your target heart rate (85% of your maximum heart rate) or complete the 13-minute time limit. Whatever stage you are at when the test ends determines your aerobic capacity and establishes your VO2 max.

VO2 max is a health and fitness term meaning the maximum amount of oxygen the body can use for energy production during exercise. It provides an index or fitness level based on the following rule: the higher the amount of oxygen that your body can use, the greater your ability to exercise for prolonged periods of time.
