WHAT IT’S REALLY ABOUT
A practical longevity playbook: move more, build strength, challenge your brain
- Dr Tommy Wood proposes a practical progression for healthy movement: sit less, walk more (ideally brisk), add resistance training, then consider HIIT, with long hard endurance work as optional for most people seeking health benefits.
- He argues that maintaining strength and functional muscle—especially fast-twitch fibers—is central to metabolic health, mobility, and fall protection as people age, and that “more muscle” isn’t automatically better than “adequate functional muscle.”
- He frames brain health as dependent on protective inputs (like exercise) and ongoing challenge, describing a “use it or lose it” pattern where learning difficult new skills and play help keep the brain engaged over time.
- On supplements, he highlights creatine as a broadly beneficial, well-studied, inexpensive option when sourced carefully, and he also emphasizes the importance of B vitamins, omega-3s, and blood-sugar stability for brain health.
- On alcohol and caffeine, he stresses nuance: alcohol offers no physiological benefit and may affect brain measures beyond very modest intake, while caffeine may be associated with benefits but can disrupt sleep and impair complex performance at higher doses.
IDEAS WORTH REMEMBERING
5 ideasBuild movement using a simple “movement pyramid,” starting with sitting less.
He outlines a sequence: sit less (including “movement snacks”), walk more (ideally brisk), add resistance training, then consider HIIT, with very long endurance work at the top as optional for most people focused on health.
Prioritize strength, not just muscle size, as you age.
He says strength declines faster and earlier than muscle mass, and that preserving fast‑twitch (type 2) fibers helps metabolic health, stability, and fall prevention—benefits he connects strongly to resistance training.
Resistance training isn’t “the gym”—it’s any progressively challenging movement against resistance.
Examples given include carrying heavy shopping bags, bodyweight squats, wall/table/floor pushups, yoga, Pilates, climbing, and daily lifting/carrying; he adds that it should be challenging and progressively harder over time.
Avoid low muscle mass; aim for functional muscle with strength proportional to size.
He describes population data suggesting that low muscle mass is the key risk signal, while simply having more muscle isn’t always better; he emphasizes strength relative to muscle as the more important predictor and notes some high-muscle measurements may reflect excess weight gain and worse metabolic health.
Creatine is presented as a broad-benefit supplement for brain, mood, and strength.
He says creatine is the one supplement he would routinely recommend to almost everyone, citing research he describes on cognitive performance (with greater benefits in older people), mood outcomes (including add-on studies with antidepressants), and strength/muscle function; he explains it as an ATP “energy buffer” and notes mechanisms aren’t fully settled.
WORDS WORTH SAVING
5 quotesResistance training of some kind.
— Dr Tommy Wood
The main thing that I try and get across is that the dose needed or the amount you do needed to, to see some benefit, again, for, for most people is really quite low.
— Dr Tommy Wood
So strength is what's important relative to muscle mass.
— Dr Tommy Wood
It’s probably the one supplement that I would routinely recommend to pretty much everybody.

Adults aren't supposed to play. We're supposed to be serious. We're not supposed to have fun.
