A: The short answer is that exercise anytime is better than no time. That said, the morning is ideal for kids because then they’re ready for the school day–alert and calm. However, with today’s school and work schedules for kids and parents, it’s often not possible to fit in. Second best is right after school–not too close to bedtime (at least 3 hours before sleep time is best), and then they are alert for homework. Try to avoid exercise in the evening when it’s time to be slowing down for the night. Time Magazine’s cover story in 2016 highlighted the benefits of exercise and I zero in on the impact for those with ADHD in Chapter 4 of my book, Getting Ahead of ADHD.
