The importance of exercise for health and long-term weight management
is now well-established. However, the critical challenge is facilitati
ng increased physical activity in the large sector of young to middle-
aged adults who are sedentary and already overweight. The psychology o
f exercise initiation and adherence in the overweight is seriously und
er-researched. However, it is possible to infer findings from the gene
ral population and from other health behaviours to develop effective e
xercise promotion strategies. Motivation and barriers to exercise, exe
rcise-related beliefs, attitudes, and self-efficacy, and the formulati
on of self-perceptions and identity towards exercise need to be consid
ered in interventions and campaigns to capture the interests of the ge
neral public. Readiness to change and behaviour change strategies need
to be considered and incorporated into social support structures to f
acilitate individual behaviour change. This could be delivered through
community, workplace and primary health care settings.
