Words explained (10)
Zone 2
Steady cardio at a pace where you can still talk in full sentences, but not sing.
Intervals
Short hard efforts with easy recovery in between, such as 30 seconds fast, 90 seconds slow.
Loaded carry
Walking while holding something heavy, like shopping bags or dumbbells.
Mobility
Moving your joints freely through their full range.
Creatine
A well-studied supplement that supports strength and muscle.
Omega-3 (EPA, DHA)
Healthy fats found mostly in oily fish such as salmon, herring and sardines.
Fibre
The part of plant foods you don't digest. It feeds healthy gut bacteria and keeps you full.
Time-restricted eating
Eating all your meals within a set window of the day, for example 8am to 6pm.

Training splits are our estimates from each expert’s published routine. Following checked October 2026.

The key differences

  • Haver puts more of the week into strength: about 55% against 45%.
  • Huberman puts more of the week into intervals: about 15% against 0%.
  • In plans in their style, Huberman's hard sessions are short sprints; Haver's are 1-minute intervals.
  • We rate the evidence behind Haver's protocol higher: strong, against mixed for Huberman.
  • Supplements that go into a plan: Huberman, omega-3; Haver, none (food first). Prescription items and personal stacks stay out of every plan.
  • Neither has a separate mobility routine; plans add 10 minutes a day of basics.

Protocols side by side

Each line is rated for the evidence behind it. “Doctor only” items never go into a plan.

Training

Andrew Huberman

  • Three resistance days a week (legs; chest, shoulders and back; arms and neck), about 50–60 minutes eachStrong evidence
  • Build toward 180–200 minutes of Zone 2 cardio a week, including one long 60–75 min sessionStrong evidence
  • One moderate cardio session of about 35 minutes at 75–80% effortSome evidence
  • One interval session: 20–30 s hard, 10 s rest, 8–12 rounds, at about 95% effortSome evidence
  • Alternate months of heavier (4–8 reps) and moderate (8–12 reps) liftingPersonal habit
  • Avoid cold-water immersion within about 4 hours after training if building muscle is the goalSome evidence

Mary Claire Haver

  • Full-body weight training at least 2 days a week (she does 3–4), progressing gradually, ideally with a trainerStrong evidence
  • Walk at least 3 days a week; beginners start with 5–10 minutes a dayStrong evidence

  • Fibre supplement if diet alone falls short of the daily targetPersonal habit
  • Check with your doctor before starting any new supplementNote

  • Creatine for possible memory and mood benefits; most of this evidence is from small or non-menopausal studiesSome evidence
  • Strength training, protein and fibre as part of reducing long-term risks such as dementia, heart disease and diabetesSome evidence

Weak spots to know

Andrew Huberman

  • Supplements: Jonathan Jarry of McGill University's Office for Science and Society (2023) argued that he promotes supplements most people do not need. He said herbal products such as tongkat ali, Fadogia agrestis and shilajit are poorly studied, and that the evidence for some claims, such as myo-inositol for sleep and anxiety, is weaker than presented.
  • Sponsorships: the podcast is funded by sponsors that include supplement, testing and wellness companies. He became AG1's paid scientific advisor in 2022, and past sponsors named by critics include InsideTracker, Thorne and Momentous. Critics say this creates a financial incentive. Neuroscientist David Berson has praised the podcast but said some researchers disapprove of certain sponsorships and supplement promotion.
  • Certainty and extrapolation: scientists including cancer biologist Joseph Zundell and immunologist Andrea Love (Slate, 2024) say he sometimes applies animal or small human studies to everyday advice and speaks outside his field. New York Magazine (2024) said he presents certainty where the science is unclear. For example, the widely quoted dopamine rise from cold comes from a small 2000 study of an hour in 14 °C water, far longer than the short dips he suggests.

Mary Claire Haver

  • Several menopause specialists, quoted in a 2024 New York Times report, said she promotes hormone use beyond official guidelines; one said patients now ask for hormones to prevent heart disease or dementia, or testosterone for general wellbeing.
  • Commercial ties, stated neutrally: she owns The 'Pause Life (a multimillion-dollar business selling supplements, programmes and online courses) and a cash-pay menopause clinic. The Menopause Society discourages doctors from selling their own products, and the advertising watchdog Truth in Advertising flagged some product claims; according to the New York Times, she then hired a consultant to review the claims on her website.
  • An independent review by ConsumerLab found some of her supplements costly for what they contain, with creatine claims that overstate the evidence and a vitamin D dose at the upper safe limit.
