Returning to your regularly scheduled ZENandTECH, Georgia and Rene discuss the benefits of exercise and how it alleviates depression, burns away stress, helps you sleep, improves your concentration, and otherwise works wonders. Plus, some app picks to help you keep track of your progress and build good habits.
