(20-04-10) New Study: LESS Cardio Gives Better

Working out for 20 minutes a day using interval exercise may provide many of the same benefits of much longer workouts done in conventional ?long-duration? style. Many experts ?recommend that children and teenagers exercise one hour every day and adults get a weekly minimum of two hours and 30 minutes of moderate intensity physical activity." "This could be activities such as brisk walking, dancing, gardening) or one hour and 15 minutes of vigorous activity (jogging, aerobic dancing and jumping rope,? CNN reported. However, a new study in the Journal of Physiology found that about 20 minutes of high-interval training provided the same benefits of longer exercise sessions that focused on endurance training. As CNN reported, ?The study suggested that quick, high-interval training may represent an alternative to endurance training to improve metabolic health and reduce the risk for chronic diseases.?
