A recent article in US Today suggest that as little as 15 minutes a day has significant health benefits. The article reports on an eight year study done on over 114,000 subjects and the results have been repeated by several other smaller studies around the world.
Fifteen minutes of moderate exercise most days of the week, like a brisk walk was shown to reduce theĀ  participants risk of death by 14 percent and added three years to their expected life span.

More is better
Of course it’s still recommended that adults do at least 30 minutes of exercise 4 – 6 days a week but this should motivate those who may feel that if they don’t have the time or are otherwise unable to do 30 minutes than there is no need to even start.
Sure more may be better but even half of whats recommended is still beneficial.
