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.
4 × 4
Four rounds of 4 minutes hard with 3 minutes easy in between. Also called Norwegian intervals.
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.
Fibre
The part of plant foods you don't digest. It feeds healthy gut bacteria and keeps you full.
Hormone therapy (HRT, MHT)
Medicine that replaces hormones that fall at menopause. Only a doctor can prescribe it.
NAD
A molecule cells use for energy. Supplements are sold to raise it, but evidence in people is limited.

The key differences

  • Wright puts more of the week into strength: about 40% against 10%.
  • Wright puts more of the week into aerobic base (zone 2): about 45% against 30%.
  • Wright puts more of the week into intervals: about 10% against 0%.
  • The Starretts put more of the week into mobility and stability: about 60% against 5%.
  • In plans in their style, the Starretts' hard sessions are 1-minute intervals; Wright's are short sprints.
  • We rate the overall evidence behind both protocols as solid.
  • Supplements that go into a plan: the Starretts, none (food first); Wright, creatine monohydrate. Prescription items and personal stacks stay out of every plan.
  • Only the Starretts have 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

Kelly & Juliet Starrett

  • Walk 8,000–10,000 steps a day, up to 12,000 if you canStrong evidence
  • Sit on the floor for at least 30 minutes a day, changing positions (cross-legged, 90/90, long sitting)Personal habit
  • Practise getting down to and up from the floor; test with the sit-and-rise testSome evidence
  • Daily deep-squat time: hold your deepest squat for five breaths as a test, plus sit-stands from a chairSome evidence
  • Daily balance practice; test standing on one leg with eyes closed (SOLEC) and putting on shoes while standingSome evidence
  • Optional rucking: start with about 2 kg for a mile, three times a week, and build up over about a monthPersonal habit

Vonda Wright

  • Two strength sessions a week. Main lifts (squat, deadlift, bench press, a row or pulldown) as 4 sets of 4 reps: heavy enough that a fifth rep is possible but not a sixth.Some evidence
  • Accessory exercises: 2–3 sets of 8–12 reps.Some evidence
  • Beginners learn the lifts with light weights first; good technique can take 3–9 months. Add about 5–10% load every 1–2 weeks.Note
  • About 20 jumps in different directions every day, for bone.Some evidence
  • About 3 hours a week of easy cardio in 45–60 minute sessions, plus short sprints twice a week (for example 4 × 30 seconds with full recovery).Some evidence
  • A walk after your biggest meal, building up to 45 minutes, and a little one-leg balance practice every day.Some evidence

Eating

Kelly & Juliet Starrett

  • About 800 g of fruit and vegetables a day (roughly six cups)Strong evidence
  • Protein about 1.5–2.2 g per kg of body weight; some later talks cite 1.8 g per kgSome evidence
  • Choose affordable protein sources that fit your budget; perfection is not requiredNote

Vonda Wright

  • At least 30 g of protein at every meal, spread through the day: about half a gram per pound of body weight (about 1.1 g per kg).Some evidence
  • About 30 g of fibre a day, a little healthy fat, and an anti-inflammatory way of eating.Some evidence
  • Log your food for three weekdays and two weekend days to see what you really eat.Personal habit

Supplements

No specific guidance in what we reviewed.

Vonda Wright

  • Creatine 3–5 g a day for strength.Strong evidence
  • Test vitamin D and supplement to reach a healthy range.Doctor only
  • Supplements aimed at clearing ageing 'zombie' cells, and the urolithin A and NAD+ precursor she has said she takes.Personal habit

Sleep & recovery

Kelly & Juliet Starrett

  • Aim for at least 7, ideally about 8, hours of actual sleep; track hours asleep for three nightsStrong evidence
  • Keep the same bed and wake times, including weekendsSome evidence
  • Be careful with caffeine and alcohol; keep phones and screens out of the bedroomSome evidence
  • Keep the bedroom cool, dark and quiet, and allow more time in bed than you think you needSome evidence

Vonda Wright

  • Put sleep first, before changing your diet or training.Personal habit

Stress & mind

Kelly & Juliet Starrett

  • Breath-hold test as a rough benchmark for tolerance of carbon dioxidePersonal habit
  • Breathe through the nose during the day and in workoutsPersonal habit
  • Optional mouth-taping at night, building up gradually from about 10 minutesPersonal habit
  • Spend about 180 minutes a week outdoorsSome evidence

No specific guidance in what we reviewed.

Weak spots to know

Kelly & Juliet Starrett

  • Several central tests rest on observational data: the sit-and-rise and one-leg balance studies show that people who do poorly die sooner, not that practising the test makes you live longer. Both studies were also in Brazilian cohorts and could not rule out other explanations.
  • Some tests have no validated scoring for the general public; the Starretts themselves describe the breath-hold test as a rough benchmark rather than a lab-grade measure, and practices such as mouth-taping have little evidence behind them.
  • Built to Move deliberately leaves out cardio and strength training; for adults over 50 those remain important for heart health and muscle, so the plan works best as a base layer rather than a complete programme. Kelly's earlier Supple Leopard was criticised by one reviewer for a trial-and-error approach rather than a systematic method.

Vonda Wright

  • The 20-jumps-a-day figure, and the 1–3% bone gain she links to it, were given without a cited study in the interview we read.
  • Her suggestions of senolytic supplements, urolithin A and NAD+ precursors rest on early, mostly small or animal studies.
  • Heavy 4-rep lifting suits most healthy women with good coaching, but beginners and anyone with osteoporosis need a slow, supervised start.
