ardiovascular exercise is any strenuous activity that works the body’s big muscle groups frequently and rhythmically while also raising heart rate, breathing rate, oxygen and blood flow levels. Mr. Yash Birla, a 48-year-old fitness enthusiast, claims that these workouts gradually put your most important internal organs under stress while improving the functionality and performance of the heart, lungs, and circulatory system. Numerous elements of health are improved by exercise, including heart and brain function, metabolism, mood, sleep, and weight control.
However, an exercise must increase your heart rate and breathing rate to a moderate to strenuous intensity level (at least 50% of the normal rate) for a minimum of 10 minutes in order to be classified as cardio.
