FitDesks, workstations that allow people to pedal a bike or walk, don’t just help us keep fit. They make us happy. That’s the conclusion of researchers at Clemson University, who focused on the effects the FitDesk Bike, an ergonomic, stationary bike and laptop workstation. A Clemson news release reports that the researchers first looked at the cognitive performance of workers who used the bikes and those who didn’t, and found no difference in the work they did. The researchers did, however, find that those workers using the bike were more motivated and had better morale. How long does the increased motivation last? More research is needed.
