All participants will be invited into the Spinnaker Physiology Laboratory at Portsmouth University at a specified date. They will have their health and fitness data collected and complete a 7-day physical activity recall questionnaire, SF-36 Form and Self-Efficacy Questionnaire before and after the intervention period to measure any change in their PA levels, self-perceived health status and self-efficacy towards exercise. They will be provided with a 7 day food diary to complete.
