Protocols side by side

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

Training

Rangan Chatterjee

Walk at least 10,000 steps a daySome evidence
Strength training twice a weekStrong evidence
Short daily glute exercises (e.g. hip extensions), a couple of minutesPersonal habit
Five-minute home workout: five moves back to back, 20 s on / 40 s off for beginners or 40 s on / 20 s off for advanced, five roundsSome evidence
Swap any move that is too hard, painful or unsafeNote

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

Weak spots to know

Rangan Chatterjee

The 4 pillar approach is broad, sensible lifestyle advice, but the evidence behind specific claims is mixed; for example, a large trial found a daily eating window added no significant weight loss on top of cutting calories.
Some targets are round rules of thumb rather than research-based numbers: the 10,000-step goal is higher than where the benefit levels off for people over 60 (about 6,000–8,000), and eight glasses of water a day is a convention, not a tested target.
He has commercial ties alongside his health advice: books, an app and a paid community, and since 2023 an advisory role with Levels, a glucose-monitoring company.

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.
