What’s the difference between physical inactivity
and sedentary behaviour?

Physical Inactivity Sedentary Behaviour
  • Physical inactivity means not meeting the minimum recommendations of the guidelines.
  • The benefits of physical activity come from being physically active.
  • Sedentary Behaviour describes any low intensity activity that you do while you are awake such as sitting or lying down.
  • An individual can meet the physical activity guidelines and still be sedentary if they sit or lie down for prolonged periods of time while awake.
  • To reduce the risk of being sedentary, you need to move more and sit less.


Exercise is physical activity that is planned, structured and repetitive for the purpose of healthy wellbeing.

Pre-Screening for Physical Activity Participation

For most people, participating in physical activity is safe. If you have never been active or have been inactive for a while, it is recommended that you complete a physical activity “Get Active” questionnaire. It can help you decide when to check with a healthcare provider before you begin.
