How Much Exercise Do You Really Need To Lose Weight?

The new guidelines issued by the American College of Sports Medicine say that 30 minutes of exercise, 5 days a week, is not enough. New research shows that 2 1/2 hours of exercise a week is effective in preventing weight gain but is not effective in weight loss. The American College of Sports Medicine now says that overweight people are more likely to lose weight and keep it off if they exercise for at least 4 hours a week. If you're trying to lose weight, you need to increase your exercise to 50 minutes a day, 5 days a week to see the results you want.
