Active Sitting Promotes Proper Posture

The concept of active sitting means sitting on an unstable surface, such as an exercise ball chair. Sitting on a ball engages your core muscles to keep you from falling off, so you are less prone to the muscle compression and hunching that occurs with extended periods of sitting in a standard office chair. If you want to replace your office chair with a balance ball chair, keep these points in mind: -Floor surface. You should have plenty of room to use a balance ball instead of a traditional office chair. A standard balance ball used as a chair ranges from 21-25" wide. Office chairs are no wider. -Size. Be sure to follow the manufacturer’s recommendations and choose the right size ball for your height. When sitting on a balance ball as a chair, your legs should form slightly greater than a 90-degree angle, with your knees slightly below your hips when your feet are flat on the floor. -Style. Some people simply sit on an exercise ball as a chair, but if you are at a computer workstation, consider a ball frame with wheels so that you can slide around your workstation more easily.
