Movement: The Most Underrated Dose
Movement is the most underrated item in this module, because it does two things at once: a single session gives you a same-day bump in executive function, exercise before the focus-heavy block, not as a reward after, and a regular habit raises the baseline over time.
In trials with ADHD, exercise improved the core executive functions across the board, with effects in the large range. And there's a useful wrinkle on what kind: open-skill activities, the ones where you're reacting to a moving, unpredictable environment, like racket sports, martial arts, or pickup basketball, came out on top, especially for impulse control, beating steady closed-skill cardio like treadmill running. The likely reason is the part that's perfect for an ADHD brain: open-skill sport forces fast read-react-decide loops and it's novel and stimulating enough to actually hold your attention, which is half the battle with any habit for you. So the prescription isn't "grind out cardio you hate until you quit in week three." It's: pick something with a ball, an opponent, or a belt, something your brain finds interesting, and use it as a focus primer, not a punishment. Now the honesty, because it's load-bearing here.
