Is sitting on an exercise ball better than a chair? The increase in the calorie burn is real but small. According to a 2008 study, performing clerical work at a desk while sitting on an exercise ball burns about four more calories an hour than the same activity in a chair, or roughly 30 extra calories in a typical workday.
How long should you sit on an exercise ball at work? Only use the equipment for a maximum of 20 minutes and alternate between an ergonomic office chair. Focus on pulling the tummy button in to keep the ball stable and keep feet flat on the floor. Make sure you purchase a ball with anti-burst technology.
