# You don’t lose muscle because you’re older. You lose it because you stopped asking for it.

> Muscle and strength slip from midlife, but they still respond to training at any age. Lift 2–3 times a week, close to failure, adding weight over time; eat 1.2–1.6 g of protein per kg a day, with a real dose at each meal; add power and balance work; sleep. Track grip, chair rises and your training log.

## The goal

Somewhere after 40, the same food and the same routine start producing a softer body and a weaker one. That’s not fate; it’s what happens when muscle gets no reason to stay. The research is unusually clear: people in their 50s, 60s and beyond still build muscle when they train hard enough and eat enough protein. This plan gives you the program.

- **Measure:** Grip · chair rises · waist · training log · optional DEXA
- **Train:** Lift 2–3×/week · close to failure · add weight · power and balance
- **Feed:** 1.2–1.6 g/kg protein · ~0.4 g/kg per meal · sleep 7+ hours

## Why it matters: Muscle is the pension you can’t buy later.

- **The default:** Walk a bit, avoid heavy weights ‘at your age’, eat a toast-and-coffee breakfast. Muscle and strength drift down every year, fat drifts up, blood sugar follows, and by 70 getting off the floor is a project.
- **The better bet:** Resistance training works at any age. In a meta-analysis of 49 studies of adults over 50, it added about 1.1 kg of lean mass on average, more with higher training volume. Strength rises faster than that, and that’s what keeps you on your feet.
- **Why muscle matters:** Muscle is where most glucose from a meal goes, it protects your joints and bones, and it’s what you fall back on in illness. Luc van Loon’s lab showed how fast it goes when you stop using it: five days in a leg cast cost young men about 4% of their thigh muscle.

## How it works: The muscle still responds. It just needs a louder signal.

Older muscle is less sensitive to both of its growth signals: training and protein. Researchers call it anabolic resistance. The answer isn’t to give up; it’s to turn both signals up. Train closer to failure, progress the load, and eat more protein per meal than a 25-year-old would need.

- **Anabolic resistance:** In Phillips’s lab, muscle building after a meal maxed out at about 0.24 g of protein per kg in younger men but needed about 0.40 g/kg in older men. Translation: a bigger protein dose per meal. Van Loon’s work adds the other half: inactivity makes it worse. A few days of disuse, from an injury, an illness or a hospital bed, blunts the muscle’s response to protein as well as shrinking it.
- **Strength before size:** Strength and power fall faster than muscle mass. Sarcopenia is now diagnosed by low strength first, which is why grip and chair-rise tests come before any scan.
- **Power:** The ability to produce force quickly, which you need to catch yourself in a trip, falls fastest of all. Training with deliberate speed keeps it.
- **Hormones:** Falling estrogen in perimenopause and menopause speeds muscle and bone loss; Stacy Sims argues that women in midlife need heavier lifting and jump training, not less. Testosterone declines more gradually in men. Training, sleep and body fat all move both.
- **Bone:** Bone responds to heavy load and impact. In the LIFTMOR trial, postmenopausal women with low bone mass did supervised heavy lifting (5 sets of 5 at over 85% of their max) twice a week and improved spine bone density, with few adverse events.
- **Insulin and fat:** Less muscle means less room for glucose. That’s why midlife muscle loss so often comes with a growing waist and rising HbA1c.

## The program: Measure. Learn the lifts. Build. Add power. Keep going.


### Measure (Week 0): Find out where you actually are.

- **Grip strength** (dynamometer, best of 3, each hand): A cheap, well-validated marker of overall strength. Many gyms, physiotherapists and pharmacies have one.
- **Chair rises** (5 rises, arms crossed, timed): From a standard chair, stand fully and sit 5 times as fast as you safely can. Over 15 seconds is a red flag for low leg strength.
- **Waist** (tape, monthly): At the belly button, after breathing out. Divide by your height; under 0.5 is the target.
- **Body composition** (optional, DEXA): Lean mass, fat mass, and, if your doctor orders it, bone density. Useful for women around menopause and anyone with a fracture history.
- **Medical check** (before heavy lifting, if relevant): If you have heart disease, uncontrolled blood pressure, chest pain on exertion, or a joint replacement, get your doctor’s OK and, ideally, a few sessions with a physiotherapist or qualified coach.

### Learn the lifts (Weeks 1–4): Groove the movements. Stay a little fresh.

- **Two full-body sessions** (2×/week, 45 minutes): Leg press or goblet squat, Romanian deadlift or hip hinge, chest press or push-up, seated row, overhead press or landmine press, a loaded carry.
- **Sets and reps** (2 sets of 10–15): Stop with about 3 reps left in the tank. The goal is form and joints that adapt, not exhaustion.
- **Progression** (every session): Add a rep or a small amount of weight when every set feels solid. Write it down.

### Build (Weeks 5–16): Now train hard enough to grow.

- **Three sessions** (3×/week, full body or upper/lower/full): Each major muscle twice a week or more. About 10 hard sets per muscle per week is a strong target; more if you recover well.
- **Sets and reps** (main lifts 3 × 6–10 · accessories 2–3 × 10–15): Take sets to within 1–2 reps of failure. Heavier and lighter loads both build muscle when the sets are hard; heavier builds more strength.
- **Double progression** (the rule for every lift): When you reach the top of the rep range on all sets, add the smallest available weight (2.5–5%) and work back up.
- **Recovery** (deload every 6–8 weeks): One week at half the sets. Recovery slows with age; planning it beats being forced into it by an injury.
- **Cardio** (150+ min/week): Canada’s movement guidelines: 150 minutes of moderate-to-vigorous activity a week, plus strength at least twice. Walking counts. Keep hard intervals away from heavy leg days. Train aerobic fitness alongside muscle, not instead of it: in a Cleveland Clinic study of 122,000 treadmill tests, the least fit had about five times the death rate of the fittest.

### Add power (Month 4 onward): Get strong and quick, not just big.

- **A heavy day** (1×/week): One main lift for 3–5 sets of 3–6 reps. Heavy load is what bone and strength respond to. Learn it with a coach first.
- **Lift fast** (every session): Lower with control, then push up as fast as you can. Speed on the way up trains power.
- **Jumps and sprints** (if your joints allow, 1–2×/week): Low box step-ups to small jumps, or short hill or bike sprints. Especially useful for women from perimenopause on, for bone. Start very small.
- **Balance** (a few minutes, most days): Single-leg stands, step-ups, walking lunges. Canada’s guidelines add balance work for everyone over 65.

### Feed it (throughout): Protein at every meal. Not just dinner.

- **Daily protein** (1.2–1.6 g/kg; up to ~2.2 is fine): PROT-AGE recommends at least 1.0–1.2 g/kg for older adults, and more for active ones. Pooled training trials stop showing extra benefit around 1.6 g/kg. With kidney disease, ask your doctor.
- **Per meal** (~0.4 g/kg, 3–4 times a day): About 30–40 g for most adults. Breakfast is where most people fall short: eggs, Greek yogurt, cottage cheese, fish, leftover meat.
- **Protein before bed** (optional, ~40 g of slow protein): In van Loon’s trial in men in their 70s, 40 g of casein before sleep raised overnight muscle building; 20 g didn’t. Cottage cheese, Greek yogurt or a casein shake. Useful if your day’s protein falls short; not a substitute for the daytime meals.
- **Real food** (protein first): Build meals on protein, vegetables and natural fats: fish, meat, eggs, dairy, legumes, nuts. Protein and fibre keep you full and flatten glucose spikes. Whole-food protein brings the leucine, fibre and micronutrients muscle needs.
- **Sleep** (7+ hours): One short night measurably worsens insulin sensitivity, blood sugar and appetite the next day. The cheapest part of the protocol, and the most skipped. Most muscle repair happens overnight. Short sleep also shifts weight loss from fat to muscle.
- **Alcohol** (keep it rare): It can blunt muscle building after training and wrecks sleep. Rare and small, never after a session.

### Supplements (optional, with your doctor’s OK): One with real evidence in older adults. Two that fill gaps.

- **Creatine monohydrate** (3–5 g a day, any time): Taken with resistance training, it added about 1.4 kg more lean mass and more strength than training alone in adults over 50, in pooled trials. Small trials hint at better memory; that evidence is thinner. It raises blood creatinine, which can make a kidney test look worse than it is, so tell your doctor you take it. Skip it if you have kidney disease, or are pregnant or breastfeeding. With lifting, it added about 1.4 kg more lean mass than lifting alone in adults over 50, plus better strength and chair-stand performance.
- **Whey protein** (20–40 g a day, only if food falls short): A convenient way to reach your protein target, nothing more. With resistance training, extra protein added a modest 0.3 kg of lean mass in pooled trials, with no further gain once total intake passed about 1.6 g per kg of body weight. If you already eat enough protein, skip it. Avoid with a milk allergy; with kidney disease, ask before raising protein. Older muscle needs more protein per meal; a scoop closes the gap when food doesn’t.
- **Vitamin D3** (1,000–2,000 IU a day, only if a blood test is low): Worth taking to correct a low level, not as insurance. In a trial of almost 26,000 adults, 2,000 IU a day didn’t prevent heart attacks or cancer. In prediabetes, pooled trials found about 15% fewer people went on to diabetes, mostly at higher doses. Stay at or under 4,000 IU a day unless your doctor says otherwise: too much raises blood calcium. Low levels are common and matter for bone and muscle. Ask your doctor whether to test.

### Retest (Every 3 months): The log tells the truth.

- **Grip, chair rises, waist** (same conditions): Repeat the baseline tests. Strength usually rises within weeks; muscle follows over months.
- **After an injury or illness** (move what you can, eat the protein): Van Loon’s disuse studies show muscle loss starts within days. Keep the uninjured limbs training, keep protein up even when appetite is low, and start rebuilding as soon as your doctor or physiotherapist allows.
- **If strength keeps falling** (your doctor): If you’re training properly and getting weaker, losing weight without trying, or falling, see your doctor. Ask about thyroid, vitamin D, medications and, where relevant, testosterone or menopausal hormone therapy.

## The rules: Short list. No exceptions.

**Choose:**
- Lifting 2–3 times a week, for good
- A training log, and a little more weight over time
- A real protein dose at breakfast
- Walking most days, balance work most days

**Avoid:**
- Light ‘toning’ weights with lots of reps left
- Skipping protein at breakfast and lunch
- Training through sharp joint pain
- Long breaks and bed rest: a few days of disuse already costs muscle, and it comes back slower each decade

**Non-negotiables:**
- Get your doctor’s OK first if you have heart disease, uncontrolled blood pressure or chest pain on exertion.
- Learn the lifts with a coach or physiotherapist if you’re new.
- Progress the load. Same weights forever is maintenance at best.
- Talk to a medical doctor before you start a supplement.

## Checkpoints: What to track, and what good looks like.

Function first. These are the numbers geriatricians use, and they predict independence better than the mirror.

| What | Target | How and when |
|---|---|---|
| Grip strength | Men ≥27 kg · women ≥16 kg (EWGSOP2 floor); higher is better | Dynamometer, best of three. Every 3 months. |
| Five chair rises | Under 15 seconds (EWGSOP2 cut-off); faster is better | Arms crossed, standard chair, timed. |
| Training log | Load or reps up on most lifts each month | Every session. |
| Waist-to-height | <0.5 | Monthly, at the belly button, after breathing out. |
| Lean mass (DEXA) | Holding or rising | Optional, yearly. Same machine each time. |
| HbA1c | <5.7% | With your regular bloodwork. More muscle usually helps it. |

The EWGSOP2 cut-offs define low strength in older adults. They’re a floor, not a goal.

## Where experts disagree: Where the experts don’t agree.

Everyone agrees older adults should lift and eat more protein. They argue about how much of each.

### How much protein after 40?

- **Moderate: PROT-AGE, Phillips:** At least 1.0–1.2 g/kg for older adults, 1.2 or more if active; the training benefit plateaus around 1.6 g/kg.
- **Higher: Lyon:** Aim well above that, with large protein doses at each meal, because older muscle is harder to stimulate and the cost of too little is high.

**Our read:** 1.2–1.6 g/kg covers most people; going higher is safe with healthy kidneys and makes it easier to hit the per-meal dose.

### Does protein timing matter?

- **Yes, spread it out: van Loon:** Older muscle needs a bigger dose each time, so how protein is spread across the day matters, and a large dose before sleep adds overnight muscle building.
- **Mostly total intake: Schoenfeld, Aragon:** In their meta-analysis of timing trials, the apparent benefit of timing all but disappeared once total daily protein was accounted for.

**Our read:** Hit the daily total first. Then make each meal count, breakfast included. A bedtime dose is a reasonable extra, not a requirement.

### How heavy should older adults lift?

- **Heavy is fine: LIFTMOR investigators, Sims:** Supervised heavy lifting and impact improved bone density in postmenopausal women with low bone mass, with few adverse events.
- **Moderate first: traditional guidance:** Light-to-moderate loads are safer for beginners and still build muscle when the sets are hard. Heavy work isn’t required for hypertrophy.

**Our read:** Start moderate to learn the lifts. Then add heavy work, coached, especially if bone is a concern.

### Do women in midlife need different training?

- **Yes: Sims:** As estrogen falls, long moderate cardio does less for body composition; heavy lifting, jumps and short sprints matter more from perimenopause on.
- **Mostly the same: general training research:** The principles of progressive overload, volume and protein apply to both sexes; women build muscle at similar relative rates.

**Our read:** The principles are the same. The emphasis on heavy load, power and bone shifts more for women in midlife.


## Limits: What this plan can’t fix.

- **The clock:** You’ll build more slowly at 60 than at 25, and recover more slowly. Most people still build, though how much varies a lot. The comparison that matters is you against you without training.
- **Hormones:** Training improves what your hormones allow; it doesn’t replace them. If symptoms point to low testosterone or menopause, ask your doctor about proper testing and whether hormone therapy fits your case.
- **Disease and injury:** Heart, kidney, joint and neurological conditions change what’s safe. Your doctor and a physiotherapist decide the limits; this plan works inside them.

*The plan rebuilds what you can rebuild. It doesn’t turn back the calendar.*

## Questions

### Can you build muscle after 40, 50 or 60?

Yes, for most people. Trials in adults over 50 show consistent gains in lean mass and larger gains in strength with resistance training. You build more slowly than at 25, and results vary, but most people build.

### How often should I lift after 40?

Two to three times a week, hitting each major muscle at least twice. Canada’s guidelines ask for strength training at least twice a week.

### How much protein do I need after 40?

About 1.2–1.6 g per kg of body weight a day, with roughly 0.4 g/kg (often 30–40 g) at each meal. Higher is fine with healthy kidneys; with kidney disease, ask your doctor.

### Is lifting heavy safe for older adults?

For most, yes, after learning the lifts and with sensible progression. Supervised heavy lifting improved bone density in postmenopausal women with low bone mass. Get your doctor’s OK first if you have heart disease or uncontrolled blood pressure.

### Should I take creatine after 40?

It has good evidence for adding strength and lean mass alongside training in older adults, and it’s safe in healthy people. Discuss it with your doctor first, especially with kidney disease.

### How do I protect my muscle after an injury or a hospital stay?

Muscle loss starts within days of disuse, and the remaining muscle responds less to protein. Keep moving whatever you safely can, keep protein up, and get back to training as soon as your doctor or physiotherapist clears you. Expect it to take longer to rebuild than it took to lose.

### What is sarcopenia?

Age-related loss of muscle strength and mass severe enough to affect function. It’s diagnosed by low strength (e.g. grip) confirmed by low muscle mass. Training and protein are the first-line response.
