How much exercise per week is recommended for adults?

The Physical Activity Guidelines for Americans state that for substantial health benefits, adults should do at least 150 minutes to 300 minutes a week of moderate-intensity aerobic activity, or 75 to 150 minutes a week of vigorous-intensity activity, or an equivalent combination.

What if I cannot manage 150 minutes a week?

The guidelines say plainly that some physical activity is better than none, and that adults should move more and sit less throughout the day. The 150-minute figure is a target for substantial benefit, not a threshold below which movement stops counting.

Is there different guidance for older adults?

Yes. Older adults are advised to do multicomponent physical activity that includes balance training as well as aerobic and muscle-strengthening activities.

Move

How much movement actually counts

Q: How often should I do strength training?

The guidelines recommend muscle-strengthening activities of moderate or greater intensity involving all major muscle groups on 2 or more days a week, in addition to aerobic activity.

Federal guidance gives real weekly targets and an important starting point: some physical activity is better than none.

The guidelines, quoted

Aerobic

150–300

minutes a week of moderate intensity — or 75–150 minutes vigorous, or an equivalent combination.

Strength

2+ days

muscle-strengthening activity of moderate or greater intensity, involving all major muscle groups.

Daily

Move more

“Adults should move more and sit less throughout the day.” Sitting is its own variable, separate from your workout.

“Some physical activity is better than none.”

That sentence is in the guidelines themselves. The 150 minutes is a target for substantial benefit — not a bar you fail to clear. Ten minutes is not nothing, and the guidelines do not pretend otherwise.

Older adults

The guidelines add one thing for older adults: weekly activity should be multicomponent, including balance training alongside the aerobic and muscle-strengthening work. Balance is trainable, and it is the component most often left out.

The lightest version of this

Almost none of the above requires buying anything. Brisk walking can count as moderate-intensity activity when it raises effort appropriately for the individual. Stairs, loaded carrying, gardening, or body-weight work may contribute to activity, but whether they meet the guideline depends on intensity, duration, load, and the muscle groups involved.

The eco version and the cheap version happen to be the same version: movement that replaces a car journey, or happens outdoors, or uses nothing manufactured. That is not a moral claim — it is just where the overlap falls.

These are population-level public health guidelines, not a personal prescription.
We have not assessed your health, and nothing here diagnoses, treats, or prevents disease.
If you have a heart, joint, or respiratory condition, or you have been inactive for a long stretch, that is a conversation with a clinician before a plan.
