Use Your Target Heart Rate for Safe and Effective Exercise
It is important to understand how to use the various ideal target heart rate zones for training to achieve specific health and fitness results. LifeSpan treadmills, elliptical trainers and exercise bikes have heart rate monitors that will read your heart rate as you workout and display your heart rate on the treadmill, elliptical or exercise bike console. The American College of Sports Medicine recommends that healthy adults strive to exercise within a heart rate range of 60-80 percent. Your optimal heart rate training zone may vary depending on your health status, any medications you are taking, and your personal health and fitness goals whether you want to manage a chronic disease, lose weight, or train for a sporting event.
Target Heart Rate Zones
Light Intensity Workouts: 35-49% Effort
Establish a good endurance base for overall fitness and to have the overall endurance to take your fitness to a higher level. Ideal training zone to maximize fat burning over a longer workout duration.
Moderate Intensity Workouts: 50-74% Effort
Develop your overall fitness by increasing your exercise intensity to maximize cardiovascular fitness along with benefiting from a greater percentage of overall calories burned per minute of exercise than would otherwise be burned exercising at a lighter level.
