You just might start to see a few more seniors lifting weights at the local gym in the future if the researchers can just get people to listen. Of course, this is not entirely new advice but every so often a compelling study comes out that really accentuates the benefits. 

In their research showing, Effect of Structured Physical Activity on Prevention of Major Mobility Disability in Older Adults, the Journal of the American Medical Association found that Seniors that weight train develop stronger bone mass and slow the process of age related muscle loss (sarcopenia). This drastically reduces the chances of fractures that come with falls.
