Why Have a Cardio Heart Rate Monitor?

I recently finished a 12-week team fitness and weight loss program at my local gym, where I learned many valuable things about fitness training and how it relates to heart health and efficient workouts. I experienced first-hand the necessity of being able to watch your heart rate with an exercise heart rate monitor, while doing various speed and incline intervals on the treadmill to have a more effective workout. A cardio heart rate monitor can tell you your heart rate, cardio training zone, calories burned and give you valuable heart smart knowledge about your body’s fitness.

Know Your Cardio Zones

After completing this fitness program, I learned that it is absolutely necessary to know what heart rate training zone you are working in to improve your workout efficiency -- to get the most benefit in the least amount of time. A heart rate monitor helps you know what cardio zone (Zones 1, 2, 3, 4 or 5) you are working in. In class, we spent most of our time working between Zone 2: the "temperate zone," Zone 3: the "aerobic zone," and some time in Zone 4: the "threshold zone." Zone 2 is commonly known as the fat burning zone, where you are exercising comfortably and body fat begins moving out of your cells. Zone 3, typically referred to as the sweat zone, involves exercising at 70%-80% of your mazimum heart rate, burning a combination of fat and carbohydrates and increasing your aerobic capacity.

Beginning to intermediate workouts include work in Zone 2 & 3 for people training to improve their aerobic fitness. Zone 4 is a tougher place to work out, where you go above your "Anaerobic Threshold (AT)." (Your AT is the level of exercise your body can sustain utilizing both fat and carbohydrates as fuel). Finally, Zone 5: the "high zone," uses the highest pecentage of heart beats and calories burned as you become more advanced and get in top physical condition. I could always count on my heart rate monitor to tell me which zone I was in and for how long, including my heart rates and recovery times. After a period of time, I got to know how my body’s heart rate responded while working between these zones, and up to AT and back down.

Know Your Heart Rate - Hands Free

In addition, a heart rate monitor can tell you your heart rate while your hands remain free of the treadmill. While we walked or ran the treadmill, the trainer called out something like “OK, now three minutes to the top of Zone 3,” or “Two minutes recovery time to the bottom of Zone 2,” as we lifted 5 to 8 pound weights, or stretched rubber bands in various routines. It’s convenient and easy to look at your heart rate monitor while you are in the middle of these routines using your arms and hands for upper body fitness. Our trainer continually stressed to a few in the class that did not yet have heart rate monitors, that the treadmill heart monitor could not be counted on to be accurate. This is especially so while a person is lifting weights at various inclines and speeds while walking or running.
