Cardio exercise equipment are mostly stationary devices. For instance, if you are on your stationary bike, then you will be pumping those pedals for the next half hour. Boredom is one reason individuals stop working out. You could have a tv in your house gym, so you can still catch up with favorite programs while sweating it out.
"Cardiovascular exercise is any type of exercise that increases the work of the and ," says Tommy Boone, PhD, a founding member of the American Society of Exercise Physiologists. "Walking, , and running are common forms of cardiovascular, or aerobic, exercise."
However, for beginners or for those who might take some time to be comfortable with cardio exercise, beginning with slow paced cardio training for sometime every day can be good enough. For those who have other medical conditions, injuries, bone and joint disorders, cardiac or respiratory disorders need to follow medical advice about the most suitable type and duration of cardio exercise.
Ideally, cardio exercises should be performed for duration of 20 minutes, during which the heart rate remains at the increased levels. These are generally performed for at least three days a week; some might enjoy five times a week. Doing 20 to 30 minutes of moderate intensity cardio training for most days in a week can reap you maximum heart-health benefits. Sports persons and athletes may perform at higher intensities for athlete level conditioning.
