What Is Cardio Exercise?
Besides hearing people groan and gripe about completing a cardio workout or touting about cardio’s incredible benefits, you may not be all that certain of exactly what cardio exercise is and what makes cardio important. Cardio, a type of aerobic exercise, does not only include physical activities like walking, running, jumping rope, and biking. It has everything to do with how your heart is beating during a workout.
So, what is cardio exercise?
Cardiovascular Exercise Definition
The definition of cardio according to the Cambridge Dictionary is, “Physical exercise that increases the rate at which your heart works.” Many professionals would add that this form of exercise should take your heart rate into its target training zone for more than 10 minutes for it to be considered a cardio workout.
Benefits of Cardio Exercise
Whether you prefer HIIT workouts involving squat jumps and mountain climbers or low-impact cardio like walking or biking, aerobic activity offers many benefits. Some of the known health benefits of cardiovascular training are:
Helps burn calories and fat for weight loss
Strengthens your heart and muscles
Helps manage or prevent high blood pressure, diabetes, and heart disease
Increases your lung and aerobic capacity
Reduces stress and helps you sleep better at night
Boosts your mood
How to Calculate Target Training Zone
So, to begin this journey into cardio exercise, we first need to know our target heart rate or target training zone. You can find this by plugging your information into your heart rate monitor or by completing the following process. Get ready, because we are about to do a lot of math. Our example will use someone who’s age is 30:
First, we need to calculate your maximum and resting heart rates. To easily calculate your maximum heart rate, simply subtract your age from 220.
Example: 220 – 30 = 190
Then, calculate your resting heart rate by locating your pulse and counting how many times your heart beats for one full minute. It is important to calculate your resting heart rate while you are resting, so we recommend doing this when you wake up in the morning before your feet even hit the floor. If that is not possible for you, just make sure that you have been resting for an extended period for best results. (During a marathon of your favorite Netflix series might be a good time!) Your resting heart rate will usually land somewhere between 60 and 100 beats per minute.
Let’s say you calculated a resting heart rate of 60.
Calculate Your Target Heart Rate Zone
Now, we need to use those numbers to calculate your target heart rate zone. Somewhere within this zone is where you will want your heart rate to land when completing a cardio workout if you want a moderate effort. Calculations for an intense workout or a light workout would have different numbers which can be found here.
First, subtract your resting heart rate from your maximum heart rate:
Example: 190 – 60 = 130
Multiply that answer by 0.70 and add your resting heart rate back in. This will be the lower end of your target heart rate zone:
Example: 130 x 0.70 = 91
Example: 91 + 60 = 151
Then, repeat that same process, but instead of using 0.70, you will want to use 0.80:
Example: 130 x 0.8 =104
Example: 104 + 60 = 164
So, for this individual, they will want their heart rate to land somewhere between 151 and 164 beats per minute during a moderate cardiovascular exercise.
How To Calculate Your Heart Rate While Training
Obviously, getting a heart rate activity tracker will make this much easier on you. If you don’t have a heart rate monitor or forget it at home, you can find out if you are in your target heart rate zone by taking a pause from your workout for 15 seconds, locating your pulse, counting your heartbeat, and then multiplying that by 4 (making a full 60 seconds). Voila! Now you know if you need to work harder. But all of this math is hurting our brains, so back to the fun stuff!
What Workouts Are Counted As Cardiovascular Exercise?
The cool thing about cardio exercise is that there are many types of cardio and you can achieve a cardiovascular workout through almost any form of physical activity. Yes, that includes strength training like weightlifting! We have talked about cardio extensively whether it is completed through interval training, Team Training sessions, group exercise, swimming, or weight training. Conventionally, though, when people think of cardio, they think of a treadmill. So, if you are looking for a quick treadmill cardio workout, here is one that we love!
