Ask ten people how much exercise they should get and you will hear ten different answers. The good news is that there is an official answer, and it is smaller than most people expect. This guide walks through what US health officials actually recommend for adults, what the terms mean, and what it looks like in a normal week.
What the Official Guidelines Say
The US Centers for Disease Control and Prevention (CDC) gives adults two simple targets. The first is aerobic activity, the kind that gets your heart rate up. The CDC recommends 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous-intensity activity a week, or an equivalent mix of the two. The second is muscle-strengthening activity on at least 2 days each week, working all the major muscle groups: legs, hips, back, abdomen, chest, shoulders and arms.
That is the whole list. It does not say you need a gym, a coach or special equipment. The full text is on the CDC adult activity page.
What Counts as Moderate and Vigorous
The CDC gives an easy way to tell the two apart, called the talk test. During moderate-intensity activity you can talk, but you cannot sing the words to your favorite song. During vigorous-intensity activity you cannot say more than a few words without stopping for breath.
Examples of moderate activity from the CDC include fast walking, water aerobics, riding a bike on level ground or with few hills, playing doubles tennis and pushing a lawn mower. Examples of vigorous activity include jogging or running, swimming laps, riding a bike fast or on hills, playing singles tennis and playing basketball. You can see the full lists on the CDC page about what counts.
What 150 Minutes Looks Like in a Real Week
150 minutes sounds like a lot until you divide it up. Here are three ways to reach it with moderate activity:
- 30 minutes a day, 5 days a week, such as a fast walk at lunch or after dinner.
- Three 10-minute walks a day on 5 days a week.
- A longer weekend activity, such as a 60-minute bike ride or hike, plus two shorter 45-minute sessions during the week.
The CDC says you can spread your activity out during the week and break it into smaller chunks of time. If vigorous activity suits you better, 75 minutes a week counts for the same target, for example three 25-minute runs.
Muscle-Strengthening Does Not Need a Gym
Many people skip the second target because they picture a weight room. The CDC list of muscle-strengthening activities is much broader. It includes lifting weights, working with resistance bands, exercises that use your own body weight such as push-ups or sit-ups, digging in a garden and doing some yoga postures.
So two short sessions a week at home can do the job. A simple routine might be squats, push-ups, a glute bridge and a plank, done in about 15 to 20 minutes. If you would like a little equipment, a mat or a set of bands is cheap and takes up almost no room. You can see a few gift-sized options in our Best Fitness & Wellness Gifts 2026 guide.
Some Is Better Than None
The most useful line in the CDC guidance may be this one: some physical activity is better than none. Adults who sit less and do any amount of moderate or vigorous activity gain some health benefits. The 150 minutes is a target, not a pass-or-fail test. If you are starting from zero, 10 minutes a day is a real start. The CDC also says that going beyond 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, brings even more health benefits.
Frequently Asked Questions
Do I need to work out every day?
No. The CDC targets are weekly, not daily. You can do your minutes on a few days or spread them across the week, and you only need muscle-strengthening on at least 2 days.
Does walking count?
Yes. The CDC lists fast walking as moderate-intensity activity. A slow stroll may not raise your heart rate enough, so try a pace where you can talk but not sing.
Do I need special gear?
No. Walking shoes are enough for the aerobic target, and your own body weight is enough for the strength target. Gear can make it more fun, but it is optional.
Who should check with a doctor first?
If you have a health condition, have not been active for a long time or are not sure where to begin, ask your doctor before you start. This guide cannot give medical advice for your situation.
The Bottom Line
The official advice for adults is simple: about 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, plus muscle-strengthening on at least 2 days. You can break it into small pieces, do it at home and start with less. Pick the version you will actually repeat, and build from there. For more ideas, browse our Fitness Zone.
