Commentary by JoAnn E. Manson, Professor of medicine at Harvard Medical School, Brigham and Women's Hospital:

The Amount of Exercise Needed to Reduce All-Cause Mortality

Conclusion: "It is a very good clinical public health message that some moderate to vigorous physical activity is substantially better than none, and that more is at least slightly better than some. We should encourage patients who are unable to meet the target, or who have to compress activity into one or two sessions per week or the weekend, to stick with it and be as active as they are able. We can expect that any activity will be better than none.
We need more research on physical activity and health, including randomized clinical trials of different types of activity, to further refine the activity guidelines. Thank you so much for your attention. This is JoAnn Manson.
