Extract

During difficult economic times, it is especially important to invest limited resources wisely. Choosing an investment strategy that will ultimately garner rewards requires strategies that turn low-risk investments into high-yield returns. This economic analogy is relevant to strategies for investing not only in the stock market but also in our health.

Summary of research findings on physical activity and health. Total minutes in a week of moderate-intensity physical activity, such as brisk walking, that can promote health or help prevent disease or death. Health outcomes are ranked from lowest to highest amount of physical activity needed. Physical activity estimates are taken from reference 5 and were converted into a common metric of minutes per week of moderate-intensity (4 metabolic equivalent task [MET] h/wk) physical activity. The lengths of the lines indicate the range of minutes associated with benefit in that health category (eg, 120-150 min/wk) and are taken from reference 5.
