Where does your endurance come from when you need it most? Do you train in advance or muster up the stamina on call? I had a football coach who loved to make us play hard till he got tired. He would then say that the forth quarter is “Gut Check” time. The fourth quarter made all the sprints, drills, and practice worth it. We usually won or lost games in the fourth quarter based upon our mental toughness, physical conditioning, and teamwork.
