Doing hard things grows the brain's tenacity hub
September 28, 2026 · 18 min read
Huberman returns repeatedly to the anterior midcingulate cortex, which appears to grow when people do things they don't want to do and is linked to willpower and resilience. It turns 'embrace the suck' into a concrete, trainable habit.
The rules, numbers and steps worth keeping in front of you.
- Huberman presents the anterior mid-cingulate cortex (aMCC) as a hub for tenacity and willpower.
- The rule: a challenge only counts if you don't want to do it. Things you already enjoy maintain, but don't build.
- Every challenge must be physically and psychologically safe.
- Dose from his AMA: at least one difficult thing a week, ideally a little every day, even five minutes.
- Finish an enjoyable run or hike with a couple of hard hill sprints that feel rough.
- Micro-sucks: one extra set, 100 jumping jacks after a run, no phone during a workout, five minutes reviewing what you just learned.
- Exercise study: sedentary adults aged 60 to 79, aerobic work one hour three times a week for six months, held or grew aMCC volume; stretching did not.
- Super-agers keep this region large, but Huberman says that link is correlation and needs more data.
- Take on a skill with no finish line, such as pottery, music or a language, with a sense of play.
- When a challenge starts to feel enjoyable, swap it for another.
- Sleep and stress management come first; they set the ceiling on willpower.
- Reward yourself with something healthy sometimes, not every time.
- Warning: anorexia shows heightened aMCC activity. Tenacity needs an off switch.
- With a history of disordered eating, talk to a clinician before restraint-based challenges.
