Want a way to burn calories, boost your mood, reduce your risk of heart disease, get a better night’s sleep and keep your brain running on top speed as you age? Then lace up your shoes and get moving, because cardiovascular exercise is the key to improving both your physical and mental health.

What Is Cardiovascular Exercise?

Whether it’s incorporated into a weight-lifting session as short bursts between exercises or as a stand-alone workout on the treadmill, elliptical or stair climber, cardiovascular exercise is defined as any physical activity that raises your heart rate and improves the function of your heart, lungs and circulatory system.

To be an effective cardio session, your chosen activity needs to keep your heart rate elevated for a specific amount of time, which is typically 20 to 60 minutes. Running, rowing, cycling and boot-camp style classes are all excellent examples of cardio workouts that target the large muscles of your body while elevating your heart rate.

When it comes to how you do cardio, you have a few options: High-intensity interval training (HIIT) involves short periods of high-intensity exercise alternating with periods of lower-intensity exercise, according to the American College of Sports Medicine. On the other end of the cardio spectrum, low-intensity steady-state (LISS) cardio focuses on performing aerobic activity at a low-to-moderate intensity (50 to 65 percent of your max heart rate) for an extended period of time.

How Much Cardio Should You Do?

The amount of cardio you do will depend on a variety of factors including your overall goals, current health status and how much time you have to devote to exercise. As a baseline, the Physical Activity Guidelines for Americans state adults should do at least 150 minutes to 300 minutes of moderate-intensity, 75 minutes to 150 minutes a week of vigorous-intensity aerobic physical activity or an equivalent combination of both.

If your primary goal is weight loss, certified personal trainer, Katrina Pilkington NASM-certified personal trainer, recommends going beyond these minimums, aiming for 45 to 60 minutes of exercise a day, five days a week, along with a healthy, reduced-calorie diet, of course.

Benefits of Cardiovascular Exercise

It’s no secret that an invigorating cardio session can make you feel fantastic, but the amazing benefits of this practically perfect form of exercise don’t end there.

1. Helps Improve Heart Health

A healthy heart can add years to your life and make performing daily activities easier, and cardio workouts help your heart stay strong and pump blood through the body more efficiently, Pilkington says.

“Gains in respiratory function can be seen with improved breathing, which means, your muscles are able to perform better when they receive blood more efficiently and increase in healthy mass,” she says.

Plus, regular cardiovascular exercise can also lower blood pressure, raise HDL cholesterol levels or “good” cholesterol, and help manage blood sugar and insulin levels, according to the National Heart, Lung and Blood Institute.

2. Can Boost Mental Wellbeing

Regular exercise can help lift your mood, decrease anxiety and improve your body’s ability to withstand and recover from stress, according to a January 2013 study published in the Journal of Preventative Medicine and Public Health.

In fact, Pilkington points out that when you exercise, your body releases neurotransmitters called endorphins, which are essential to reaping the mental health benefits of exercise. “Cardio workouts (and physical activity or movement in and of itself) can improve mental clarity and reduce feelings of stress or depression.”

3. Burns Calories and Can Aid in Weight Loss

As long as you’re following a healthy diet, cardiovascular exercise can help you meet your weight-loss goals. Depending on the type of activity, duration and intensity level, you can expect to burn anywhere between 150 and 1,000 calories per session. Other factors that contribute to the number of calories you burn doing cardio exercise include your body size and composition, gender, and age.

Here are some common methods of cardio and the number of calories a 155-pound person can burn in 30-minutes, according to Harvard Health Publishing.

  • Walking (4 mph/15-minute mile): 167 calories
  • Jog (10-minute mile): 223 calories
  • Cycling (16 to 19 mph): 446 calories
  • Swimming, vigorous: 372 calories

To maximize your calorie burn, consider adding two sessions of HIIT to your weekly cardio training. HIIT uses bouts of high-intensity exercise alternated with short rest periods to maximize calorie burn. It also allows you to get the most amount of work done in the least amount of time.

4. May Reduce the Risk of Certain Diseases

Sweating it out on the treadmill or hitting the road for a cycling session just might reduce your risk of developing certain diseases. In addition to protecting your heart, according to Harvard Health Publishing, cardio training has also been linked to a reduction in the risk of:

  • Diabetes
  • Asthma
  • Arthritis
  • High blood pressure
  • Several forms of cancer, including esophagus, lung, kidney, colon, head and neck, rectum, bladder, breast and two cancers of the blood (myeloma and myeloid leukemia)

Weight-bearing cardio exercise such as walking, jogging, hiking, stair-stepping and elliptical machines also reduce your risk of developing osteoporosis. That’s because your bones respond to weight-bearing exercise by becoming stronger, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

5. Aids in Slowing Age-Related Cognitive Decline

The benefits of physical activity for brain health are impressive. In addition to reducing the risk of dementia (including Alzheimer’s disease), cardio also improves cognition, which leads to a higher processing speed, better memory and an increased ability to retrieve and use information, according to the World Health Organization’s (WHO) 2019 Guidelines on Risk Reduction of Cognitive Decline and Dementia.

6. Can Lead to Better Sleep

Better sleep is something we can all use a lot more of, especially with the high levels of stress many of us experience. The good news is regular physical activity, and more specifically, cardiovascular exercise can result in a better night’s sleep, according to the National Sleep Foundation.

From improved sleep efficiency and reduce sleep latency (taking less time to fall asleep) to better sleep quality and more deep sleep, moving your body during the day has a significant impact on how you sleep at night. Just make sure you’re not working out too close to bedtime or you might actually have trouble falling asleep.
