new research published in the Lancet will motivate them a bit. The report shows that just 15 minutes of physical activity per day reduces a person's risk of death by 14% and increases life expectancy by 3 years compared with inactive people. Every additional 15 min of daily exercise beyond the minimum amount of 15 min a day was shown to further reduce all-cause mortality by 4% and all-cancer mortality by 1%. Individuals who were inactive had a 17% increased risk of mortality compared with individuals in the low-volume group. The study followed more than 400,000 individuals - 20 years and older - from 1996 through 2008.
