Dr. Tommy Wood, an MD and PhD neuroscientist, shares his insights on brain health and cognition. He emphasizes that boosting brain function is crucial at any age, not just for preventing dementia. Tommy outlines optimal learning strategies and daily habits for cognitive improvement, advocating for engaging exercises like martial arts and racket sports that yield significant brain benefits. He also discusses the importance of nutrients, hydration, and social connections in maintaining brain health, making a compelling case for a holistic approach to mental fitness.

ANECDOTE

Doug's Portuguese Push

Doug Larson credits Tommy Wood for motivating him to learn Portuguese to boost his long-term brain health.
Tomas's advice pushed Doug to embrace being a 'white belt' and start daily learning.

ADVICE

Use Daily Touchpoints

Use daily touchpoints to build habit even if deep sessions are less frequent.
Maintain small daily practices (e.g., Duolingo) to keep momentum and psychological engagement.

INSIGHT

Exercise Type Maps To Brain Function

Different exercise types target different brain regions and functions.
Aerobic work especially benefits the hippocampus and memory, with high-intensity protocols showing lasting structural gains.

In this episode of Barbell Shrugged, Doug Larson is joined by longtime co-host Travis Mash and new co-host Dr. Mike Lane for a return visit from one of the show's most popular guests, Dr. Tommy Wood. Tommy breaks down the core thesis of his new book, The Stimulated Mind (releasing March 24), which uses dementia prevention as the headline but is really about boosting cognition at every stage of life. The crew sets the tone early: brain health is not "old people stuff," it's performance, learning, and resilience, built daily through how you live and how you train.

Tommy makes the case that "optimization" only works when it fits real life, and that the brain adapts like the body: sleep, nutrition, and exercise support it, but you still have to "train the brain" with demanding learning and skills. He outlines a practical learning dose-response, roughly 30–90 minutes of deep challenge per session, 2–3 times per week as a sweet spot for consolidation, while acknowledging the power of daily touchpoints for habit formation (Doug's Duolingo streak and the "don't break the chain" approach). From there, they go deep on exercise modalities and cognition: aerobic work and interval training improving hippocampal function (memory), high-intensity work potentially driving brain benefits through lactate → local BDNF, and coordinative/open-skill sports (racket sports, dancing, martial arts) producing outsized brain returns for the same physical strain.

The conversation closes with a fast but important run through risk, genetics, and lifestyle: Tommy explains ApoE4 as a risk multiplier that's highly environment-dependent, amplifying bad inputs (inflammation, poor metabolic health) but also amplifying the benefits of doing the basics well. They hit the big nutrition levers for cognition; omega-3s, key B vitamins (methylation), vitamin D, iron, plus polyphenol-rich foods (berries, cocoa, coffee/tea), and squash the common "red wine" rationalization by emphasizing net outcomes (sleep and brain volume matter). Finally, Tommy emphasizes the under-rated keystone: social connection and pro-social behavior, arguing that the Mediterranean "diet" is really a Mediterranean lifestyle, and that isolation can erase many of the benefits of even a perfect nutrition plan.
