I doubt that I am the only person who gets tired of hearing about all of the benefits of aerobic exercise when it is something that I cannot do. Today I heard on National Public Radio’s Talk of the Nation that non-aerobic exercise is also beneficial. http://www.npr.org/templates/story/story.php?storyId=122620054 Muscle contractions are important to regulation of blood glucose and fat. People who spend large amounts of time sedentary, whether in front of a television or behind a desk, are at increase risk of death. Any type of movement is beneficial in this respect. This does not negate the benefit of regular exercise, nor does a daily exercise program negate the harmful effects of prolonged periods of sitting. Everybody stretch now!
