Vigorous exercise should provide a significant challenge to your cardiorespiratory system. This statement is TRUE.

Vigorous exercise also known as a hard exercise is a physical activity that produces a higher heart rate and rapid breathing. Activities like running, jogging, hill walking, aerobic dance, lap swimming, and martial art are examples of vigorous exercise.

It is recommended to do vigorous-intensity exercise for 25 minutes a day for three days a week or 75 minutes per week. Signs that you are doing vigorous exercise are: you are breathing rapidly and your heart rate is substantially increased and you are likely to be sweating. In general, the higher your heart rate during physical activity, the higher the exercise intensity.

Vigorous exercise offers greater cardiovascular benefits than moderate-intensity workouts. A study showed walking at a moderate pace only minimally reduced coronary artery disease risk, regardless of frequency or duration. Doing exercises in balance is important, overdoing it can increase injury and soreness. You can combine moderate exercise with vigorous exercise. Start with a moderate or light exercise then gradually vigorous-intensity.
