John Ratey & Spark: The Complete Guide
Exercise remodels attention and mood — walk before the next nootropic
Spark (2008) is psychiatrist John Ratey’s case that aerobic work changes the brain: attention, mood, and memory. The Naperville school story is the famous chapter. This guide sends you to Zone 2 and Lieberman before another focus capsule. It is not permission to stop psychiatric medication.

Move, Then Pills
Moderate EvidenceBlood flow and BDNF are the mechanism chapters. A morning walk is the protocol. A nootropic stack on 2,000 steps is the miss.
See Zone 2 for the easy aerobic dose and Exercised for why voluntary training feels optional.
What 2008 Does Not Cover
Moderate EvidenceAttia still owns VO2 max and strength on this site. Spark is the brain why, not a reason to skip the barbell after 50.
Keep vs Skip
Moderate EvidenceKeep: scheduled aerobic work, sleep, a clinician if mood or attention is a diagnosis. Skip: stopping prescribed psychiatric medication because a hardcover praised running.
