Build a plan from bothSee the protocols
Words explained (11)
Zone 2
Steady cardio at a pace where you can still talk in full sentences, but not sing.
VO2 max
The most oxygen your body can use in hard exercise. A good measure of fitness; higher is better.
Intervals
Short hard efforts with easy recovery in between, such as 30 seconds fast, 90 seconds slow.
4 × 4
Four rounds of 4 minutes hard with 3 minutes easy in between. Also called Norwegian intervals.
Hypertrophy
Muscle growth.
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.
Mitochondria
The parts of your cells that turn food and oxygen into energy.

The key differences

  • Galpin puts more of the week into strength: about 50% against 30%.
  • Patrick puts more of the week into aerobic base (zone 2): about 40% against 30%.
  • Patrick puts more of the week into intervals: about 30% against 15%.
  • In plans in their style, both use 4-minute intervals (Norwegian 4 × 4) for hard sessions.
  • We rate the overall evidence behind both protocols as strong.
  • Supplements that go into a plan: Galpin, creatine monohydrate, caffeine before training; Patrick, omega-3, vitamin d with k2. Prescription items and personal stacks stay out of every plan.
  • Only Patrick has a mobility or movement routine of their own.

Protocols side by side

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

Training

Andy Galpin

  • Strength: the 3–5 rule – 3–5 exercises, 3–5 sets of 3–5 reps, 3–5 minutes' rest, 3–5 days a week, every rep done with full intentStrong evidence
  • Muscle growth: at least 10 hard sets per muscle group a week, each within 1–2 reps of failure; 15–20 sets for more experienced liftersStrong evidence
  • Add load gradually for strength, roughly 3–5% a week, and keep the same main exercises for about 6–12 weeks before changing themSome evidence
  • Moderate, conversational-pace cardio of about 150–200 minutes a week for general healthStrong evidence
  • Warm up for about 5–7 minutes, up to 10 if you are stiff or olderPersonal habit
  • Run a simple fitness test battery about once a year (for example grip strength, jumps, push-ups and an estimate of VO2 max) and retest weak areas more oftenSome evidence

Rhonda Patrick

  • At least 10 minutes of vigorous exercise a day; she suggests this should replace the 10,000-step goalSome evidence
  • Norwegian 4 × 4: four 4-minute intervals, hard but not all-out (the original protocol uses about 85–95% of max heart rate), with 3-minute recoveries, 1–2 times a week; build up graduallySome evidence
  • Keep daily walking too: step benefits level off around 6,000–8,000 steps a day for older adultsStrong evidence
  • Strength training at the start of most sessions, supported by enough proteinStrong evidence
  • Short 'exercise snacks' (e.g. 1 minute of squats or burpees) spread through the daySome evidence

Eating

Andy Galpin

  • Total daily protein matters more than exact timing around workoutsSome evidence
  • Daily fluid baseline of about 30 ml per kg of body weightPersonal habit
  • During training: drink about 2 ml per kg of body weight every 15–20 minutes; afterwards replace about 125% of the weight lostSome evidence
  • For long or very hard sessions, start at about 60 g of carbohydrate per hourStrong evidence

Rhonda Patrick

  • Protein about 1.6 g per kg of body weight a day to support resistance trainingStrong evidence
  • Whole-food meals built on vegetables, berries and a protein source (eggs, fish, poultry, red meat)Personal habit

Supplements

Andy Galpin

  • Creatine monohydrate 3–5 g a day; larger people may need moreStrong evidence
  • Creatine takes about 3–4 weeks to saturate muscle at normal doses; a loading phase is optionalNote
  • Caffeine about 1–3 mg per kg roughly 30 minutes before exercise; performance tends to drop above about 5 mg per kgStrong evidence

Rhonda Patrick

  • Omega-3 (EPA + DHA) about 2 g a day as a starting point; aim for an Omega-3 Index of 8% or more and retest after about 4 monthsSome evidence
  • Take omega-3 with a meal that contains fat; higher doses need care (bleeding risk, atrial fibrillation, medicines)Doctor only
  • Vitamin D with vitamin K2 in the eveningSome evidence
  • Creatine 10 g a day (her own dose, above the usual 3–5 g)Personal habit
  • Multivitamin, magnesium, nicotinamide riboside and PQQ as part of her personal stackPersonal habit

Sleep & recovery

Andy Galpin

  • After training, lie down for 3–10 minutes with eyes covered and breathe slowly through the nose (for example box breathing) to switch into recovery modeSome evidence
  • Cold-water immersion can ease soreness but may blunt muscle growth, so keep it away from strength sessions if muscle is the goalSome evidence
  • Hot baths for next-morning stiffnessPersonal habit
  • Pair one physical recovery tool (compression, light movement, a swim) with one breathing practice rather than chasing every gadgetPersonal habit
  • Watch three markers – performance, physiology (resting heart rate, HRV) and how you feel; five or more days of decline is a sign to back offSome evidence

Rhonda Patrick

  • Sauna 4–7 times a week, around 20 minutes at roughly 79 °C, based on Finnish cohort dataSome evidence
  • Schedule heat sessions a couple of hours before bedPersonal habit
  • After short sleep, vigorous exercise such as intervals or weights can help blood-sugar controlSome evidence
  • Cold exposure mainly in summer; she does not keep it up in winterPersonal habit

Brain health

Andy Galpin

No specific guidance in what we reviewed.

Rhonda Patrick

  • Push hard enough to raise lactate: hard exercise raises BDNF, a growth factor linked to learning and mood (human evidence still early)Some evidence
  • Frequent sauna use is linked with lower dementia risk in Finnish men (observational)Some evidence
  • Keep omega-3 status up; she links it to brain health and ageing markersSome evidence

Weak spots to know

Andy Galpin

  • Much of his detailed advice (hydration formulas, carbohydrate per hour, caffeine dosing) is built for athletes and hard training; it needs scaling down for most adults over 50.
  • Several recovery tools he discusses, such as compression, cold and heat, have modest or mixed evidence, and he himself notes cold immersion may reduce muscle gains.
  • His fitness-test benchmarks are practical rules of thumb rather than age-adjusted clinical norms.

Rhonda Patrick

  • The sauna benefits she highlights come mainly from one observational cohort of middle-aged men in eastern Finland. It shows an association, not proof that sauna causes the benefit; women were not included, and commentators noted the reason for the link is unclear (heat, relaxation, lifestyle or social contact).
  • An epidemiology newsletter (The Edge of Epidemiology, 2025) argued that some of her headline numbers, such as vitamin D cutting dementia risk by about 40%, rest on observational studies and overstate what is known; genetic and trial evidence is mixed.
  • She often builds a case from biological mechanisms (e.g. lactate and BDNF, nutrients and serotonin). Several of these ideas are supported mostly by animal or small short-term human studies, as her own episodes acknowledge.
