Words explained (9)
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.
Hypertrophy
Muscle growth.
Mobility
Moving your joints freely through their full range.
Leucine
A building block of protein that helps switch on muscle building. Meat, fish, eggs, dairy and soy are rich in it.
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.

The key differences

  • Norton puts more of the week into strength: about 65% against 45%.
  • Huberman puts more of the week into aerobic base (zone 2): about 40% against 25%.
  • In plans in their style, Huberman's hard sessions are short sprints; Norton's are 1-minute intervals.
  • We rate the evidence behind Norton's protocol higher: strong, against mixed for Huberman.
  • Supplements that go into a plan: Huberman, omega-3; Norton, creatine monohydrate, whey protein, caffeine before training. 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

Layne Norton

  • Lift weights consistently, year after year, and take sets close to failureSome evidence
  • Exercise improves health markers even when it does not change your weightStrong evidence
  • Track daily steps while dieting: everyday movement tends to drop as calories fallSome evidence
  • His PHAT programme: 5 days a week, two heavy 'power' days plus three higher-rep hypertrophy daysPersonal habit

Eating

Andrew Huberman

  • Has described eating his first meal around 11 am–noon (2021)Personal habit
  • Protein and fats at lunch. Carbohydrates mainly on training days and at dinnerPersonal habit
  • Gives no protein target of his own. His guests suggest about 1.6 g per kg a dayNote

Layne Norton

  • Track calories and protein; food labels can be ~20% off, but consistent tracking still shows your true intake over timeSome evidence
  • Weigh yourself each morning and compare weekly averages, not single daysSome evidence
  • Protein about 1.6 g/kg a day; up to ~2.2 g/kg when dieting or very leanStrong evidence
  • Choose a diet style you can sustain; low-carb and low-fat work equally well with calories and protein matchedStrong evidence
  • Fibre about 15 g per 1,000 kcalSome evidence
  • Seed oils are fine: replacing saturated fat with polyunsaturated fat lowers LDL and heart riskSome evidence

Supplements

Andrew Huberman

  • Omega-3: 1–3 g of EPA a daySome evidence
  • Sleep stack 30–60 min before bed: magnesium threonate 145 mg or bisglycinate 200 mg, apigenin 50 mg, theanine 100–400 mg. Add one at a timePersonal habit
  • Has taken the greens powder AG1 since 2012. AG1 is a long-time podcast sponsorPersonal habit
  • Alpha-GPC 300 mg before mental work or training (personal use)Personal habit
  • Herbal hormone products such as tongkat ali (200–600 mg) or Fadogia agrestis (about 600 mg) only with blood tests before and after, and taken in cyclesDoctor only
  • Not a fan of melatonin except occasionally for jet lagNote

Layne Norton

  • Tier 1 – creatine monohydrate 3–5 g a day; loading is optional; timing does not matterStrong evidence
  • Tier 1 – whey protein 20–40 g per serving (about 2–3 g leucine) to help reach daily proteinStrong evidence
  • Tier 1 – caffeine 3–6 mg/kg about 45–60 min before training; lower doses still help alertnessStrong evidence

Sleep & recovery

Andrew Huberman

  • Outdoors within 30–60 min of waking: about 10 min of light if sunny, 20 if cloudy, 30–60 if very overcastSome evidence
  • No caffeine in the last 8–10 hours before bedStrong evidence
  • Delay the first caffeine 90–120 minutes after waking (his own practice)Personal habit
  • Keep regular sleep and wake times, and a cool, dark bedroomStrong evidence
  • Avoid bright overhead light from about 10 pm to 4 amSome evidence
  • Keep naps under 90 minutes, or use a 10–20 minute rest practice (NSDR or yoga nidra) insteadPersonal habit

Layne Norton

  • Avoid caffeine late in the day; it can harm sleep even if you fall asleep normallyStrong evidence
  • Carb timing matters little on average; if carb-heavy meals make you sleepy, move themNote
  • Poor sleep and unmanaged stress are bigger problems than small nutrition detailsNote

Stress & mind

Andrew Huberman

  • Cyclic sighing, a breathing practice with long exhales, for about 5 minutes a daySome evidence
  • Deliberate cold: about 11 minutes a week in total, split into 2–4 sessions of 1–5 minutes, early in the daySome evidence
  • Weekly heat and cold session: 3–5 rounds of about 20 min sauna and about 5 min cold bath (7–10 °C)Personal habit
  • Morning walk outdoors, which he says helps calm the stress responsePersonal habit

Brain health

Andrew Huberman

  • Focused work in 90-minute blocks with distractions removedPersonal habit
  • Takes omega-3 EPA for brain health, mood and focusSome evidence
  • Caffeine at 1–3 mg per kg about 30 minutes before a mental task, not after about 2 pmSome 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.

Layne Norton

  • Commercial ties: he co-founded Outwork Nutrition, which sells whey protein and products containing creatine — overlapping with his Tier 1 list — and co-founded the paid Carbon Diet Coach app and the BioLayne coaching business. He has also disclosed past research funding from the National Dairy Council, the National Cattlemen's Beef Association and the Egg Board.
  • Reverse dieting, which he helped develop and popularise, had no published controlled trials supporting it as of 2021; its use rests mainly on coaching experience.
  • His relaxed view of seed oils is contested by others in the health space. On The Drive (2026), Peter Attia presented the strongest case against seed oils for a debate after the booked guest declined, while saying his own view is close to Norton's; debate continues over older trials and LDL oxidation.
