How heavy
From our Vonda Wright profile
Wright and Sims favour heavy, low-rep sets for midlife women; Israetel advises older lifters to do most sets in the 10–20 rep range to lower the injury risk.

Vonda Wright vs Mike Israetel
Vonda Wright (orthopaedic surgeon) and Mike Israetel (sport physiologist (phd)) side by side: how they train, eat, supplement and sleep, how strong the evidence is, and how to build a plan from either or both.
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.
- Hypertrophy
- Muscle growth.
- 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
- Israetel puts more of the week into strength: about 65% against 40%.
- Wright puts more of the week into aerobic base (zone 2): about 45% against 25%.
- In plans in their style, Wright's hard sessions are short sprints; Israetel's are 1-minute intervals.
- We rate the overall evidence behind both protocols as solid.
- Supplements that go into a plan: Wright, creatine monohydrate; Israetel, 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.
Where they disagree
How heavy
From our Mike Israetel profile
Israetel steers older lifters toward 10–20 reps; Wright and Sims favour heavy sets of about 4–6 reps for midlife women.
Protocols side by side
Each line is rated for the evidence behind it. “Doctor only” items never go into a plan.
Training
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
Mike Israetel
- For the average person, about 30 minutes of training twice a week gives the best return on time.Some evidence
- After 40: most sets in the 10–20 rep range, some at 20–30, and 5–10 reps only rarely, because heavy low-rep sets raise the risk of injury.Some evidence
- Train each muscle twice a week, starting with 1–2 hard sets per muscle per session, and add a set the next week if you recovered well.Some evidence
- Lower the weight slowly and pause for 1–2 seconds at the bottom.Some evidence
- Warm up more: three warm-up sets (light, medium, heavier) before the first working set, and 1–2 before each later exercise.Personal habit
- Add weight in small steps: rarely more than about 2.5 kg or one rep per set at a time.Personal habit
- Choose joint-friendly exercises with a high stimulus, for example a hack squat instead of a heavy back squat.Some evidence
- Take a planned easy week every 4–6 weeks, and a lower-volume month about every 5 months.Personal habit
Eating
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
Mike Israetel
- If you want to gain muscle, only gain weight when you are lean: about 0.25 kg a week for 4–8 weeks, then a fat-loss phase.Personal habit
- Stay under about 20% body fat while gaining, come back to about 15% afterwards, and get blood tests after gaining phases.Personal habit
Supplements
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

Weak spots to know
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.
Mike Israetel
- Most of his content is aimed at bodybuilders and younger lifters; advice for people over 40 is a smaller part of it.
- Many specific numbers, such as when to take easy weeks or how fast to add sets, are coaching rules of thumb rather than findings from trials.
- He sells training programmes and diet products through RP, the company he co-founded.
