Research shows that exercising within a specific heart rate range is the optimal way to
monitor exercise intensity and achieve maximum results. That is the idea behind the Life
Fitness Heart Rate Zone Training exercise program.
Zone Training takes the guesswork out of working out by identifying specific ranges, or
zones, in which to maintain a heart rate to achieve maximum exercise results according to
personal goals. In short, Zone Training all but eliminates under- and over-training by allowing
you to target your heart rate to your individual fitness objectives.
For instance, if the primary goal is to burn fat, exercise at a level between 60% and 75% of
your theoretical maximum heart rate
† . To improve cardiovascular condition, you should work
out at 75% to 85% of your theoretical maximum heart rate.
Life Fitness offers two exclusive programs designed to take full advantage of the benefits of
Heart Rate Zone Training: Fat Burn and Cardio. Vary the focus of exercise activities by
switching between the Fat Burn and Cardio program at any time during a workout or by
entering a new target heart rate with the keypad.
Both the Fat Burn and Cardio programs measure heart rate. As you exercise, grasp the
Lifepulse sensors (if so equipped) when prompted or simply wear an optional telemetry heart
rate chest strap (on telemetry equipped models) and your heart rate will be transmitted to the
on-board computer. The resistance level will automatically adjust to maintain the target heart
rate based on your actual heart rate.
