Andrew Huberman: Professor of neurobiology and ophthalmology at Stanford School of Medicine and host of the Huberman Lab podcast, which delivers science-based tools for everyday life.
What this episode covers
In this solo episode, Andrew Huberman explores the psychology and neuroscience of tenacity and willpower. He weighs the long-running debate over whether willpower is a limited resource depleted by glucose (Baumeister's ego-depletion theory) against Carol Dweck's finding that beliefs about willpower determine whether glucose matters. He then makes the case that a single brain structure, the anterior mid-cingulate cortex, is the central hub generating tenacity and willpower. Finally, he lays out research-backed protocols, especially doing hard things you resist ("micro sucks") and cardiovascular exercise, to physically build up this brain area and its carryover across all domains of life.

Big reveals from this episode
- Names the anterior mid-cingulate cortex as the brain hub for tenacity and willpower, a structure he says most neuroscientists are unaware of.
- Carol Dweck's 2013 PNAS study found glucose only boosts self-control if you believe willpower is a glucose-limited resource.
- Joseph Parvizi's 2013 study directly stimulated the cingulate in awake patients, who reported a felt sense of an oncoming storm they must push through.
- Argues the same brain hub for willpower carries over across all domains, so building it in one area transfers to others.
- Claims things you already enjoy (like cold showers if you love them) will NOT increase willpower; you must add resistance.
- Suggests the anterior mid-cingulate cortex may underlie the very 'will to live,' linking it to superagers and longevity.
- Cites a brand-new pre-clinical neuron study showing stress relief itself acts as a reward that reinforces tenacity.
Worth remembering
- The formal study of willpower as a limited resource dates back only about 20-25 years to Roy Baumeister's 'ego depletion' work.
- In the classic experiment, subjects resisting freshly baked cookies later quit an impossible puzzle sooner than those resisting radishes.
- Giving subjects a ~150-calorie glucose drink between hard tasks maintained or even increased their willpower performance.
- High-achieving individuals show higher resting-state activity in the anterior mid-cingulate cortex than lower achievers.
- People with anorexia nervosa show heightened cingulate activity when avoiding rather than eating food.
- Superagers maintain an anterior mid-cingulate cortex significantly larger than their age-matched peers.
- Citing Robert Sapolsky, Huberman says a major function of testosterone is to make effort feel good.
- A 2006 study found three weekly hours of moderate cardio over six months maintained or grew the cingulate in older adults.
- Huberman coins 'micro sucks', small unwanted tasks like 100 jumping jacks after a run, to train the willpower hub.
- Anorexia nervosa is described as the most deadly of all psychiatric conditions.
