How much exercise should adults get each week?
Fitness & Exercise
Adults should get at least 150 minutes of moderate-intensity aerobic activity plus two days of muscle-strengthening activities each week, according to the CDC Physical Activity Guidelines for Americans.
The Centers for Disease Control and Prevention recommends this exercise framework for substantial health benefits. The 150 minutes can be achieved through 30 minutes of moderate activity five days per week, or you can break it into shorter sessions of at least 10 minutes throughout the week. Alternatively, adults can substitute 75 minutes of vigorous-intensity aerobic activity for the moderate activity requirement.
Moderate-intensity activities include brisk walking, water aerobics, ballroom dancing, or general gardening. Vigorous activities encompass jogging, running, swimming laps, or playing basketball. The key indicator is that moderate exercise allows you to talk but not sing during the activity, while vigorous exercise makes conversation difficult.
The muscle-strengthening component should work all major muscle groups including legs, hips, back, abdomen, chest, shoulders, and arms. These activities should be performed on two or more non-consecutive days per week. Examples include weight lifting, resistance band exercises, push-ups, sit-ups, or yoga.
For even greater health benefits, the CDC suggests increasing aerobic activity to 300 minutes of moderate-intensity or 150 minutes of vigorous-intensity exercise weekly. This enhanced level provides additional protection against chronic diseases and supports weight management more effectively.
Adults with chronic conditions should consult healthcare providers about appropriate exercise modifications, as some conditions may require adjusted intensity levels or specific exercise types. The guidelines apply to healthy adults aged 18-64, with separate recommendations existing for older adults and individuals with disabilities.
Research consistently shows that meeting these exercise recommendations reduces risk of cardiovascular disease, type 2 diabetes, certain cancers, and premature death while improving mental health and cognitive function.
