Strength training for older adults promotes longevity

"The researchers looked at data from the National Health Interview Survey (NHIS) where nine percent of participants reported meeting the twice-a-week guidelines for strength training. “That’s only a small fraction of the population, but it’s actually higher than we had anticipated,” Kraschnewski said.

The respondents were followed for 15 years through their death certificate data. The researchers found that those who partook in strength training at least twice a week had a 46 percent lower risk of death, 41 percent lower risk of cardiac death, and 19 percent lower risk of death by cancer."
