Recommendations Call for 250 Minutes of Physical Activity a Week for Significant Weight Loss, 150 Minutes a Week to Maintain Weight

You may need to block out more time for the gym. 

Adults need at least 250 minutes per week – equal to 50 minutes of exercise 5 days a week – to lose significant weight, according to the latest recommendations from the American College of Sports Medicine (ACSM).

If you are trying to maintain your weight rather than lose, you may still be OK with the 30-minute workouts. The ACSM recommends that adults participate in at least 150 minutes per week of moderate-intensity physical activity to prevent significant weight gain. Overweight and obese adults, however, are more likely to reach their goals with at least 250 minutes. The report also recommends strength training as part of the exercise regimen.

The recommendations are published in Medicine & Science in Sports & Exercise. They are in line with the recent recommendations published by the U.S. Department of Health and Human Services.

Weight management is an important public health issue, the report says. More than 66% of U.S. adults are either overweight or obese. People can reduce their risk for chronic diseases with as little as a 2% to 3% reduction in excess body weight.
