Researchers have established that obesity is associated with increased mortality risk. However, a new study suggests that the severity of this risk may have been underestimated.
Published in Population Health Metrics (2014; doi:10.1186/1478-7954-12-6), the study looked at mortality and body mass index in nonsmoking adults aged 50–84. Data was pulled from the National Health and Nutrition Examination Surveys (1988–1994 and 1999–2004) and linked to the National Death Index through 2006.

Did you ever have to cue audiocassette tapes before teaching aerobics? (You might’ve heard about playing albums in class, but that was before your time.)

If you answered yes to either or both of these questions—and you joined the fitness industry before or around the time step aerobics became popular—you might be a member of Generation X (also referred to as Gen X). This group, now in their 30s and 40s, has influenced the fitness industry through many permutations.
Since this survey was last published in January 2009, the national unemployment rate has increased from 6.1% (August 2008) to 9.6% (October 2010), which equates to about 14.8 million unemployed individuals in the United States (U.S. Department of Labor 2010a). However, the silver lining for fitness professionals is that even though the national job market has declined, our industry is still expected to see better-than-average growth (29%) in positions over the next decade (2008–2018) (U.S. Department of Labor 2010b).
