HEART RATE TARGET ZONES
The Sportline Duo 1010 Heart Rate Watch allows you to select from 3 preset Heart Rate Target Zones
(AEROBIC, FAT BURN and HEALTH) and 1 user-defined Target Zone. The watch tracks time IN, ABOVE
and BELOW Target Zone during exercise.
SELECTING YOUR TARGET HEART RATE ZONE
Losing weight and managing to keep it off is a lot easier when you exercise in your target heart rate
zone. To determine your target heart rate zone, first subtract your age from 220. That’s an estimate of
your maximum heart rate. To get the most out of any exercise program, you should target 50% to 85%
of your maximum heart rate depending on your fitness level and objectives.
Health Zone: 50% - 65% of maximum heart rate.
This zone is ideal for fitness beginners on a low to moderate intensity program. Exercising in this zone
reduces blood pressure and cholesterol.
Fat Burning Zone: 65% - 75% of maximum heart rate.
Exercising in this zone strengthens the cardiovascular system and nearly all the calories burned are
from fats.
Aerobic Zone: 75% - 85% of maximum heart rate.
Reaching this zone requires more intense aerobic activity and is perfect for fitness enthusiasts
working to burn maximum calories from fat and carbohydrates. Cardiovascular strengthening,
increased metabolism and elevated caloric burn are the primary benefits.
