The purpose of this study is to test feasibility for the delivery and perceptions of a lifestyle model for middle-aged and older adults by involving participants in its development. The goal of the program is to reduce sedentary behaviour, increase physical activity, and increase strength and balance. An optional walking program will be run in parallel to emphasize the importance of moving more. Participants will be asked to fill out questionnaires on course delivery, content and effect throughout the program and 2-3 recorded interviews throughout the study. We will collect measurements of physical performance before and after the program.
