A Little Is Better Than Nothing

Good news for those of us who are short on time another study has backed up the benefits of short bouts of exercise. Since many people have difficulty setting aside the recommended 30 to 60 minutes for exercise each day, researchers from Ireland decided to check out if three 10-minute "brisk" activity periods would do the job. By taking two groups of exercisers, one doing three short bouts of activity throughout the day and one doing a single longer bout, the study found that three 10-minute sessions yield similar health benefits to one continuous 30-minute routine. Both groups saw slight decreases in total cholesterol and increases in "good" cholesterol and cardiovascular fitness. There were also similar decreases in anxiety and stress reported by participants in both groups. Unfortunately for many, these results also mean no more excuses about lack of time!
