Exercising to Keep the weight off!!!!!!

Twenty minutes of moderate exercise a day is suffient to produce cardiovascular benefits, but for women who want to keep the pounds off its not nearly enough says Los Angeles Times. Harvard researches followed 34,000 relatively healthy middle-aged and older women from 1992 to 2007, and found that only those who exercised an hour a day managed to keep from steadily gaining weight as they grew older. That's three times more exercise than the 150 minutes a week that's necessary to lower the risk of heart disease and other illnesses. "You can still do much for your health with a lower level of exercise," says study author Dr. I-Min Lee. "But if you want to exercise for weight control, it's 60 minutes a day."





By exercise, researchers dont only mean time spent on a Stairmaster; brisk walking, yoga, and other daily activities count, too. The researchers noted that there is an alternative to spending seven hours a week exercising, if your goal is to avoid weight gain: Steadily cut down on calories as you get older.
