Research shows that regular physical activity offers numerous health benefits including, but not limited to, the regulation of blood pressure, management of anxiety and depression and the prevention of weight gain. ACSM provides recommendations and guidelines for physical activity and exercise based on the latest science and insights from health professionals.
ACSM is known throughout the industry as the "gold standard" when it comes to exercise recommendations. Thanks in large part to the publication of ACSM's Guidelines for Exercise Testing and Prescription, now in its 11th edition. GETP has been a staple resource for professionals since 1975.
The Physical Activity Guidelines for Americans, 2nd edition, published by the U.S. Department of Health and Human Services, gives the most current physical activity recommendations for all age groups and special populations.
ACSM and CDC recommendations state that:
- All healthy adults aged 18–65 years should participate in moderate intensity aerobic physical activity for a minimum of 30 minutes on five days per week, or vigorous intensity aerobic activity for a minimum of 20 minutes on three days per week.
- Every adult should perform activities that maintain or increase muscular strength and endurance for a minimum of two days per week.
Aerobic activity or “cardio” gets you breathing harder and your heart beating faster. From pushing a lawn mower, to taking a dance class, to walking or biking to the store – these types of activities and more count. As long as you’re doing aerobic physical activities at a moderate- or vigorous-intensity, they count toward meeting the aerobic guideline.
Intensity is how hard your body is working during a physical activity.
Moderate-intensity aerobic physical activity means you’re working hard enough to raise your heart rate and break a sweat. One way to tell if it’s a moderate-intensity aerobic activity is that you’ll be able to talk, but not sing the words to your favorite song. Here are some examples of activities that require moderate effort:
- Walking fast
- Doing water aerobics
- Riding a bike on level ground or with few hills
- Playing doubles tennis
- Pushing a lawn mower
Vigorous-intensity aerobic activity means you’re breathing hard and fast, and your heart rate has gone up quite a bit. You may use the Talk Test to gauge the intensity of your aerobic physical activity. If you’re being active at a vigorous level, you won’t be able to say more than a few words without pausing for a breath. Here are some examples of activities that require vigorous effort:
- Jogging or running
- Swimming laps
- Riding a bike fast or on hills
- Playing singles tennis
- Playing basketball
If you are doing moderate-intensity physical activity, such as walking or hiking, you can talk, but not sing during the activity.
Build Up Over Time
If you want to do more vigorous-level activities, slowly replace
those that take moderate effort like brisk walking with more vigorous activities like jogging. Learn more about getting started with physical activity to improve health.
You can do moderate- or vigorous-intensity aerobic activity, or a mix of the two, each week. A rule of thumb is that 1 minute of vigorous-intensity activity is about the same as 2 minutes of moderate-intensity activity.
Some people like to do vigorous activity because it gives them about the same health benefits in half the time. If you haven’t been very active lately, however, increase your physical activity level slowly. If you have a history of a chronic disease, consider telling your doctor you are planning to increase your physical activity, including moving to more vigorous activity. You need to feel comfortable doing moderate-intensity activities before you move on to more vigorous ones. Learn more about additional types of physical activity that are right for you.

For most healthy adults, the Department of Health and Human Services recommends these exercise guidelines:
- Aerobic activity. Get at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity. The guidelines suggest that you spread out this exercise during the course of a week. To provide even greater health benefit and to assist with weight loss or maintaining weight loss, at least 300 minutes a week is recommended. But even small amounts of physical activity are helpful. Being active for short periods of time throughout the day can add up to provide health benefit.
- Strength training. Do strength training exercises for all major muscle groups at least two times a week. Aim to do a single set of each exercise using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.
Moderate aerobic exercise includes activities such as brisk walking, biking, swimming and mowing the lawn. Vigorous aerobic exercise includes activities such as running, heavy yard work and aerobic dancing. Strength training can include use of weight machines, your own body weight, heavy bags, resistance tubing or resistance paddles in the water, or activities such as rock climbing.
As a general goal, aim for at least 30 minutes of moderate physical activity every day. If you want to lose weight, maintain weight loss or meet specific fitness goals, you may need to exercise more.
Reducing sitting time is important, too. The more hours you sit each day, the higher your risk of metabolic problems. Sitting too much can negatively impact your health and longevity, even if you get the recommended amount of daily physical activity. And some research has found that people who've lost weight may be more likely to keep off the lost weight by sitting less during the day.
Short on long chunks of time? Even brief bouts of activity offer benefits. For instance, if you can't fit in one 30-minute walk during the day, try a few five-minute walks instead. Any activity is better than none at all. What's most important is making regular physical activity part of your lifestyle.
