The Importance of Good Posture

3. Correct Sitting Posture

To sit with a healthy posture, keep both feet on the floor or a footrest. While sitting, the legs should never cross and the ankles should remain in front of the knees. Additionally, there should be a slight gap between the seat of the chair and the back of the knees. To support the back, lean against a chair and ensure the backrest is making contact with the lower and middle back. In many chairs, the upper back will not make contact with the chair. Keep the shoulders loose and the forearms parallel to the ground.
