Exercise is usually sold as the thing that steals study time. An hour at the gym is an hour not spent with the books — or so the anxious student reasons, and skips the workout before exams. The research says this reasoning gets it exactly backwards: properly timed physical exercise is one of the most reliable, free, side-effect-free cognitive enhancers available, and it measurably improves the very sessions you sacrifice for.
Exercise before studying measurably boosts both memory and attention, and pairing the two yields a striking academic advantage.
