Weekly 150 Minutes of Moderate Activity

The CDC and the NHS both set the adult aerobic target at 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous activity, or an equivalent mix, ideally spread over most days.

The protocol

• Target: 150 minutes of moderate-intensity activity a week, or 75 minutes of vigorous-intensity activity, or an equivalent combination.
• Pacing: spread over 4 to 5 days or every day, for example 30 minutes on five days.
• Intensity: moderate means you can still talk but not sing.
• Equivalence: one minute of vigorous activity counts about the same as two minutes of moderate activity.
• Addition: muscle-strengthening on at least 2 days a week is a separate guideline and does not count toward the aerobic minutes.
• Duration: ongoing.

What you get

• The CDC and the NHS both set the adult aerobic target at 150 minutes of moderate activity a week.
• Muscle-strengthening on at least 2 days a week is advised in addition.

Contraindications

• Adults with chronic health conditions or a disability should check with a health care professional about the type and amount of activity that is right for them; the CDC applies the same weekly aim only to those who are able.
• Anyone who is currently inactive should build up gradually rather than starting at the full weekly total.
• Anyone with symptoms, an injury, or advice from a clinician to limit exertion should follow that advice first.

Evidence level

High. Two national health agencies, the CDC and the NHS, independently state the same weekly target and the same talk-test definition of moderate intensity.
