Improve your posture and reduce fatigue at home or in the office with the DynaFlex BC0112 ball fitness chair. Ergonomically designed to align your body while relieving tension and stress on your back, the fitness chair provides a healthy, proactive sitting position, thereby engaging your postural muscles and allowing you to experience the benefits of movement while remaining seated. The chair works by constantly encouraging some type of motion, helping keep you alert throughout the day. That’s because the unstable surface encourages your body to find the most efficient way to balance. Since the best way to sit is with proper spinal alignment, you’ll have a natural tendency to sit upright with good posture, thereby improving your balance, posture, core stability, and core strength all in one. A ball chair even helps improve circulation, letting you sit back without back stiffness and fatigue. Best of all, research has shown that seemingly minor physical activity–such as active sitting–can burn up to 350 extra calories a day.
