Current guidelines recommend 150 minutes of moderate intensity exercise per week for better health. But a new study published in the journal Circulation suggests that you can have much greater health benefits – and a longer lifespan – by doubling that amount. Harvard researchers analyzed data from over 100,000 adults over a period of 30 years. The people with the lowest mortality performed 150 to 300 minutes per week of vigorous physical activity, or 300 to 600 minutes of moderate physical activity, up to twice as much as doctors currently recommend. Any amount of exercise every day is, without a doubt, better than none, but if you can do even more, you will almost certainly experience even better health.
