Physical activity for adults

Summary

Adults need at least 150 minutes a week of moderate aerobic activity (or 75 minutes vigorous, or a mix) plus muscle-strengthening on 2+ days. It can be split into short chunks; any activity beats none.

General information, not medical advice. See a clinician about your own situation; in an emergency call 911 (US).
