Myth: "Before I work out, I should stretch to help prevent injuries."
A 2004 literature review by the Centers for Disease Control and Prevention confirmed what many studies had shown: Stretching will not prevent injuries. Moreover, stretching is not a warm-up. You're better off performing the exercise you're about to do at a much lower intensity for about 10 minutes - walking or jogging slowly before you run; gently swinging the club before a game of golf.
"There's actually not much data on the benefits of stretching, although it's like God, mother and apple pie - everyone is for it," says Dr. Carl Foster, president of the American College of Sports Medicine.
I love debunking myths, and I have a terrible attention span. I think Mythbusters would be my favorite show, except it's an hour too long. So this combination of debunking an age-old myth and finding a shortcut makes it my favorite news item of the day.
Don't you find it hard to believe though? I honestly don't exercise much, but when I used to run a lot, I would always feel that when I didn't stretch I felt more uncomfortable quicker. Maybe that warm-up technique would have worked better.
