How Much Cardio Do You Actually Need Each Week?

How much cardio do you need each week? For general adult health, the useful target is usually 150–300 minutes of moderate-intensity aerobic activity, 75–150 minutes of vigorous-intensity activity, or an equivalent combination across the week.

How Much Cardio Do You Need Each Week?

For most adults, the public-health recommendation provides a practical answer: aim for 150–300 minutes of moderate-intensity aerobic activity, 75–150 minutes of vigorous-intensity activity, or an equivalent mix each week. The World Health Organization uses this range for adults aged 18–64, while current U.S. guidance likewise recommends 150–300 minutes of moderate aerobic activity for substantial health benefits. [2] [3]

That does not mean 150 minutes is a pass-or-fail line. If you are currently doing very little, adding some regular activity is still worthwhile. CDC guidance emphasizes that some physical activity is better than none and that the weekly total can be spread across the week. [1]

This cardio target is one part of your overall activity. If you want to see how aerobic exercise and strength work fit together, our guide to weekly exercise recommendations explains the broader picture.

What Actually Counts as Cardio?

Cardio is a common name for aerobic activity: movement that increases your breathing and heart rate for a period of time. It does not have to happen on a treadmill, and it does not have to feel extreme.

Depending on intensity, activities such as brisk walking, jogging, cycling, swimming, dancing, hiking and many recreational sports can contribute to your weekly aerobic activity.

Moderate vs. Vigorous Cardio: What's the Difference?

The amount of cardio you need each week depends partly on intensity. Moderate activity requires noticeable effort but is less demanding than vigorous activity. Vigorous activity makes you work considerably harder.

A practical way to judge intensity is the talk test. During moderate activity, you can usually talk but not sing comfortably. During vigorous activity, speaking more than a few words without pausing for breath becomes difficult.

Does Walking Count as Cardio?

Yes—walking can count when the pace reaches moderate intensity. This is one reason brisk walking is such a useful option: it requires little equipment, can fit into everyday life and can be divided across the week.

For example, five 30-minute brisk walks would add up to 150 minutes of moderate aerobic activity. CDC guidance specifically uses 30 minutes of brisk walking on five days as one example of meeting the weekly aerobic recommendation. [1]

A slow, relaxed walk still adds movement to your day, but whether it counts toward the moderate-intensity target depends on how hard your body is working.

Do You Need to Do Cardio Every Day?

No. The recommendation is based on your total activity across the week rather than requiring a cardio workout every day. CDC examples show that the target can be divided in several ways, including 30 minutes of moderate activity on five days or 25 minutes of vigorous activity on three days. [4]

This flexibility matters because a sustainable routine has to work around the rest of your life. You might prefer shorter sessions on more days, or fewer longer sessions.

How Should You Split Cardio Across the Week?

There is no single schedule everyone needs to follow. Start with the weekly target, then divide it into sessions you can realistically repeat.

The schedule is less important than accumulating an appropriate amount of activity consistently. If you are returning after a long period of inactivity, you do not need to jump straight to the full weekly target. Our guide to starting to work out after a break explains how to build back gradually.

How Much Cardio Should Beginners Do?

If you are not active right now, start with an amount that feels manageable and build from there. WHO guidance advises inactive adults to begin with small amounts and gradually increase frequency, intensity and duration. [2]

That might mean beginning with short walks or another comfortable aerobic activity several times during the week. Once that feels routine, you can gradually add time or increase the pace rather than changing everything at once.

How Does Cardio Fit With Strength Training?

A balanced activity routine includes both aerobic activity and muscle-strengthening work. Current adult guidelines recommend strength training that involves the major muscle groups on at least two days each week in addition to aerobic activity. [1]

You do not have to choose between cardio and strength. They address overlapping but different parts of physical fitness, and both can fit into the same week.

If you are deciding how to organize the strength side of your routine, see our guide to how often you should strength train.

What Does a Balanced Week Look Like?

One simple approach is to spread moderate cardio through the week and place strength sessions between or alongside those days.

This example reaches 150 minutes of moderate aerobic activity and includes two strength-training days. It is not a prescription. Your activities and schedule can look different while still meeting the same general target.

Is More Cardio Always Better?

More is not automatically better for every person or every goal. WHO guidance indicates that adults can gain additional health benefits by going beyond 300 minutes of moderate activity or 150 minutes of vigorous activity when appropriate, but that does not mean everyone needs to pursue the highest possible amount. [2]

For general wellness, it is more useful to build a sustainable routine than to treat exercise as a contest. Your available time, recovery, health, other physical activity and goals all matter.

So, How Much Cardio Do You Need Each Week?

How much cardio do you need each week? A practical general-health target is 150–300 minutes of moderate aerobic activity, 75–150 minutes of vigorous activity, or an equivalent combination. You can spread that activity across the week in the way that best fits your routine.

If you are below that amount today, you do not have to transform your schedule overnight. Start with regular movement you can maintain, then build gradually.
