Verutum RX : Exercise pumps you full of feel-good endorphins, so (believe it or not) your body actually begins to crave gym time. No matter how chaotic your environment is or how stressful you work is, you should never let your body or mind suffer. This is a big reason I recommend most busy people complete either full body workouts, or a body part split that covers the entire body in only 2 workouts.
