As if we didn't need any more evidence that regular exercise is good for you. Now it seems that even small amounts, as little as 15 minutes, can add years to your life.
The current recommendations for exercise rest around 150 minutes per week. Yet researchers in Taiwan observing over a period of 8 years noticed that even at 15 minutes per day, deaths from any cause were dropped significantly. It may not seem like it, but you can do a lot in 15 minutes.
15 minutes is enough for a tough circuit or a brisk walk around the block. 15 minutes in plenty of time to get 4 or 5 hard sets of just one exercise in, or even to simply take some time to stretch out your stiff muslces. I think it's safe to say that most people, including myself, wish we had more time to work out and take care of ourselves. Use this info as a reminder that "something" is, in fact, better than "nothing".
