Cardiorespiratory Endurance Activities

Cardiorespiratory endurance activities test and improve the body's ability to sustain dynamic exercise, using large muscle groups, over time. During this moderate to high-intensity level of exercise, the body's circulatory and respiratory systems—the heart and lungs—must supply fuel and oxygen to the muscles.

Activities such as running, swimming, and bicycling improve cardiorespiratory endurance.

We usually hear the term shortened to just "cardio," or "aerobic."

You might also hear these activities called cardiorespiratory fitness, aerobic fitness, aerobic endurance, cardiopulmonary fitness or a cardio workout. These terms refer to this whole category of exercise, in which the primary goal is to boost the heart rate. In contrast, other forms of exercise like resistance training aim primarily to build muscle and bone strength. Exercises that target flexibility and balance are also important. 

How Much Cardio Exercise Do I Need?

The U.S. Centers for Disease Control and Prevention recommends both aerobic (cardio) and resistance exercise for most Americans. Specifically, the department recommends that children and teens get at least 60 minutes of physical activity every day, and most of it should be moderate to vigorous aerobic exercise.

For adults, the CDC suggests that "adults should do at least 150 minutes (2 hours and 30 minutes) a week of moderate-intensity, or 75 minutes (1 hour and 15 minutes) a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity aerobic activity."

But you don't need to—and in fact should not—do all this exercise at once: "Aerobic activity should be performed in episodes of at least 10 minutes, and preferably, it should be spread throughout the week," according to the guidelines.

Cardiorespiratory Endurance Activities You Can Do With Your Kids

Running, swimming, and biking builds cardiorespiratory endurance.

The same goes for brisk walking and climbing stairs. But if you're exercising with young ones, you may want to turn your cardio workout into a game. Activities like these can help you both collect and enjoy your daily physical activity:

• Sports: Chasing a ball or another player is great cardio exercise. Think kickball, basketball, lacrosse, soccer, tennis and other racquet sports. Winter sports like ice skating, cross-country skiing, snowshoeing and even sledding (the "walking uphill" part) also require cardiorespiratory endurance.
• Playground games: Many classic, kid-favorite backyard games, especially tag (in its many forms) require plenty of running around, which definitely gets hearts pumping. 
• Dancing: Remember aerobics classes? Recreate the calorie burn with your own music and movies. Coordination is not required; movement is what really matters.
• Hopping, skipping, and twirling: Break out the jump ropes and hula hoops for a cardio workout that is kid-friendly and lots of fun, but also challenges the heart and lungs.
