Participants' motivation to exercise will first be determined according to stages of the HAPA model. Those who identify as pre-intenders (no intention to exercise) will receive intervention strategies that focus on changing motivation to be physically active. Those identified as intenders (willing to exercise but have not started) will focus on providing resources and behavioural strategies to commence physical activity. Lastly, those identified as actors (already exercising) will receive intervention strategies that help participants maintain or improve PA behaviour.
