How much exercise adults actually need each week, according to the CDC

How much exercise adults need each week, per the CDC: 10 points covering the 150-minute target, vigorous options, strength training and why some movement beats none

Ask how much exercise adults need, and the CDC gives a specific answer: at least 150 minutes of moderate-intensity physical activity every week. The agency's own illustration breaks that into 30 minutes on each of five days. The guidance around that number also allows several ways to reach it.

The figure comes from "Adult Activity: An Overview," a page in the CDC's Physical Activity Basics section dated Dec. 20, 2023. It was produced by the National Center for Chronic Disease Prevention and Health Promotion. The page draws on the current Physical Activity Guidelines for Americans.

Physical activity, in the CDC's definition, is anything that gets the body moving. The agency says activity supports both physical and mental health. It calls being active one of the most important things a person can do for health.

The weekly target can be met in more than one way. Vigorous-intensity activity offers a shorter route: 75 minutes a week instead of 150 moderate minutes. The CDC also expresses that figure as 1 hour and 15 minutes. Its example of vigorous activity is jogging or running. Its example of moderate-intensity activity is brisk walking. An equivalent combination of moderate and vigorous activity, spread over two or more days a week, also counts.

None of it has to happen in a single session. The CDC says the minutes can be spread across the week and broken into smaller chunks. The guidelines also include muscle-strengthening activity alongside the aerobic minutes.

The 150-minute mark is a floor, not a ceiling. Going past 150 minutes of moderate activity, 75 minutes of vigorous activity or an equivalent mix brings additional health benefits, according to the CDC. For adults who fall short of the target, the agency's message is that some activity is better than none. The agency says people who sit less and do some moderate or vigorous activity still gain some health benefits. The CDC sums up that idea in four words: "Move more, sit less."

The 10 slides that follow take the guideline apart one piece at a time. They cover the baseline itself, what counts as activity and the vigorous and combined routes. Others address strength work, the CDC's walking and running examples and how to schedule the minutes. The last two explain why some movement helps and what doing more adds.

150 minutes of moderate-intensity activity a week is the CDC baseline for adults

Adults need at least 150 minutes of moderate-intensity physical activity every week, according to the Centers for Disease Control and Prevention. The CDC presents that figure as a minimum, not a ceiling.

The target appears on the CDC's Adult Activity: An Overview page, part of its Physical Activity Basics section. The National Center for Chronic Disease Prevention and Health Promotion is the page's content source. Its weekly targets draw on the Physical Activity Guidelines for Americans.

In hours, 150 minutes equals two and a half hours. A full week contains 10,080 minutes. The CDC baseline therefore takes up roughly 1.5% of an adult's week.

The goal is measured per week, not per day. Adults have room to decide when the minutes happen. The CDC says the time can be spread across the week and broken into smaller chunks.

Moderate intensity is the qualifier that defines this benchmark. The CDC's example of a moderate-intensity activity is brisk walking.

The moderate route is one of three ways to reach the CDC's aerobic target. The others are 75 minutes of vigorous-intensity activity or an equivalent combination of moderate and vigorous activity. The CDC's adult guidance also includes muscle-strengthening activity alongside the aerobic minutes.

The baseline is not a pass-or-fail line. The CDC says going beyond 150 minutes of moderate activity brings additional health benefits. Adults below the target who sit less and do some moderate or vigorous activity still gain some health benefits, according to the agency.

What the CDC counts as physical activity for adults

The CDC defines physical activity as anything that gets the body moving. Under that wording, movement outside a formal exercise session counts too.

The definition appears in the CDC's overview of adult activity, a page built on the Physical Activity Guidelines for Americans.

The CDC ties movement to both physical and mental health. It says physical activity supports each one. The agency also describes being active as one of the most important things a person can do for their health.

The wording names no gym, sport or piece of equipment. It does not limit activity to a particular setting or type of movement. The CDC's weekly targets sort movement by intensity instead. Moderate-intensity effort, illustrated........
