Life Fitness X3 5 user manual Fat Burn, Cardio

FAT BURN

The FAT BURN workout is designed to maintain a user’s heart rate at 65 percent of the theoretical maximum rate† for optimal results. Throughout the workout, the user grasps the hand pulse sensors or wears a wireless heart rate chest strap. The console continuously monitors and displays the heart rate, adjusting the intensity level of the exercise bike to reach and maintain the target*. This system eliminates over- and under-training, and it maximizes the aerobic benefits of exercise by using the body's fat storage for fuel. The user must wear a wireless heart rate chest strap.

CARDIO

The CARDIO workout is virtually identical to FAT BURN; however the target heart rate is calculated at 80 percent of the theoretical maximum†. The higher target promotes cardiovascular improvement by placing a heavier workload on the heart muscle. The user wear a wireless heart rate chest strap.

†Defined by the American College of Sports Medicine's "Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual’s age.

*Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's THR for the FAT BURN workout is 117. This workout targets 65 percent of the maximum, so the equation would be (220-40)*.65=117. A 20-year-old user’s THR is 130, so the equation would be (220-20)*.65=130.
