It is said that 75% of the US population is estimated not to engage in 30 minutes of low-to-moderate physical activity. This estimation fluctuates according to <u><em>age, gender and occupation.</em></u> Another contributing factor to having less physical activity is the <em>rate of unemployment.</em> People who are unemployed find it hard to focus on exercise or physical activity.
