Physical inactivity is a significant public health issue, as low levels of physical activity are associated with increased risk of non-communicable diseases (e.g., heart disease, diabetes, certain cancers), chronic disease risk factors (e.g. obesity and hypertension), anxiety and depression, and premature mortality^[1]-[2]. The World Health Organization (WHO) reports that physical inactivity is the fourth leading risk factor of global mortality, estimating 3.2 million deaths globally attributable to inactivity^[3]. In addition to the impact on the lives of the individual, there are societal costs. For example, the economic impact of physical inactivity in Canada in terms of chronic disease, obesity and health care costs is estimated at CAD $3.9 billion annually^[4].
