21 answers covering everything from basics to advanced usage.
// Basics
What is sarcopenia and when does it start?
Sarcopenia is the medical condition that results when muscle mass, strength, and function decline to a clinically significant threshold — it's not just normal aging but a diagnosable condition requiring intervention. It becomes most visible in the 70s but begins as early as the late 30s and early 40s, which is why building reserve decades earlier matters so much.
What are myokines and why do they matter?
Myokines are hormone-like signaling molecules released by contracting muscle. They're believed to mediate the reduced risk of chronic disease — including cancer, cardiovascular illness, and neurodegeneration — associated with exercise. This is why muscle is called an endocrine organ, and why improving muscle health in any part of the body generates systemic benefit beyond just that muscle.
What are Type 1 and Type 2 muscle fibers?
Type 1 fibers are slow-contracting and fatigue-resistant, built for endurance like walking and standing — they're relatively preserved with aging. Type 2 fibers are fast-contracting and built for power, force, and quick reactions like stair-climbing or catching a fall. Type 2 fibers decline first and fastest, which is why someone can walk for hours but struggle to rise quickly from a chair.
What is biological reserve and the stress event staircase?
Biological reserve is the accumulated muscle mass, strength, and function you carry into a stress event like surgery or illness. After such events, people don't automatically return to their previous baseline — many settle lower. Each stress event drops the baseline another step, like descending a staircase. Reserve determines whether you stay above the disability line, where independence is lost.
// How To
How do I run the three functional reserve tests at home?
Sitting Rising Test: lower to the floor and rise using as little hand or knee support as possible. 30-Second Sit-to-Stand: from a chair with arms crossed, count full stand-and-sit reps in 30 seconds. One-Leg Stand: balance on one leg for 10 seconds, eyes open then closed. Always have someone nearby for safety, and record results to track trends.
How do I structure protein to hit the threshold?
Calculate 1.2–1.6 g per kg of lean body mass daily, then divide into 25–30 g servings across 3–4 meals. Each meal must reach roughly 25–30 g so blood amino acids cross the threshold that triggers muscle protein synthesis. Small snacks of 10–15 g never hit threshold and waste the protein. Use whey or pea protein isolate to fill gaps.
How do I add sprint interval training safely?
Do 10–30 second near-maximum bursts followed by 1–3 minutes of recovery, 4–5 rounds, at least once weekly — you can add these to existing walks as hill sprints. Explosive moves like box step-ups, kettlebell swings, and jump squats also qualify. Only add these after building a foundation of strength and fitness, and prioritize recovery since Type 2 fibers need more repair time.
How often should I do resistance training?
The minimum is 2 resistance sessions per week covering all major muscle groups; 3 is better. Use progressive overload — gradually increase weight, reps, sets, or frequency. Favor heavier weights with lower reps for strength and power, alternate heavy with light-to-moderate days, and allow 48–72 hours between heavy sessions. Supervised training is strongly preferred for older adults and beginners.
What recovery practices does this method require?
Recovery is non-negotiable: consume quality protein post-exercise for muscle protein synthesis, carbohydrates to replenish glycogen, adequate hydration and electrolytes, and foam rolling to reduce tightness. Sauna after resistance training helps via increased perfusion. Avoid cold plunges for several hours post-lifting. Allow 48–72 hours between heavy sessions, and give Type 2 fibers extra repair time after sprint intervals.
// Troubleshooting
My endurance is great but I struggle on stairs — what's wrong?
You're likely experiencing Type 2 fiber decline masked by preserved Type 1 endurance. Walking, cycling, and golf preserve slow-twitch endurance fibers but do almost nothing for the fast-twitch power fibers that fade first with aging. Add progressive-overload resistance training and sprint intervals to target Type 2 fibers directly, and run functional tests to quantify the gap.
I eat plenty of protein but I'm still losing muscle — why?
You may be spreading protein in small doses that never hit the 25–30 g threshold per meal, so much of it is wasted for muscle building. Anabolic resistance means aging muscle needs more protein per serving, not less. Restructure to 25–30 g per meal 3–4 times daily, and pair it with progressive-overload resistance training, since protein without a training stimulus builds little.
Will a high-protein diet damage my kidneys?
In individuals without kidney disease, moderate-to-high protein intake up to 2–2.5 g/kg/day is handled efficiently and does not damage healthy kidneys. The real risk is crowding out fiber, fruits, and vegetables. If you have kidney disease, protein and creatine must be physician-supervised. Also stop creatine two weeks before blood tests to avoid falsely elevated creatinine readings.
Is it too late to build muscle in my 70s?
No — muscle adapts to progressive overload at any age, though older adults must progress gradually with attention to technique, and supervised training is strongly preferred. Even a 2-repetition improvement on the 30-Second Sit-to-Stand is clinically meaningful. Start with low-to-moderate loads, raise protein to threshold, add creatine if cleared, and track trends rather than chasing perfection.
// Comparisons
How does this method compare to generic longevity advice?
Generic longevity advice focuses on lifespan and vague 'stay active' guidance. This method centers healthspan and treats muscle as the earliest, most reliable marker of accelerated aging. It's specific: prioritize Type 2 fibers, hit the protein threshold, use progressive overload with heavy loads, build reserve before stress events, and measure with DEXA and functional tests — turning intention into trackable protocol.
How does this compare to relying on HRT or testosterone for muscle?
Hormone therapy is not the primary intervention here. In menopause, heavier resistance training and increased protein — not HRT — are the main levers, though HRT prescribed for other reasons may modestly augment training results. In men, resistance training and protein efficiently offset gradual testosterone decline without replacement unless both clinical symptoms and low blood levels are present. Hormones supplement, never replace, exercise and nutrition.
Should I use a DEXA scan or a body composition scale?
DEXA is the gold standard — it measures muscle, fat, and bone mineral density with very low radiation (less than a cross-country flight) and is recommended annually for tracking trends. If DEXA is unavailable, use a body composition scale under consistent conditions (same time of day and hydration). Either way, calculate protein from lean body mass, not total weight, and track trends over time.
// Advanced
How do GLP-1 medications affect muscle and how do I protect it?
On GLP-1s, 20–30% of weight lost may be lean mass. Counter this with resistance training 2–3x/week, protein at 1.6–2.0 g/kg lean mass in 25–30 g meals, gradual rather than rapid weight loss, and aggressive baseline tracking via DEXA every 3–6 months. Start resistance training before or alongside the medication — don't wait. Note weight regained after stopping tends to return as fat, worsening body composition.
Why should I avoid cold plunges after lifting?
Cold plunges immediately after resistance training cause vasoconstriction that reduces amino acid deposition to muscle and blunts the adaptation gains from your session. For women specifically, temperatures below 50°F may further mitigate muscle growth. Sauna after resistance training is beneficial because it increases muscle perfusion. Save the cold plunge for several hours later or on non-lifting days.
How does anabolic resistance change my protein needs?
Anabolic resistance is the age-related drop in muscle's responsiveness to protein — older adults need more protein per serving than younger adults to trigger the same muscle-building effect. Yet older adults typically eat less protein, not more. This is why hitting the 25–30 g per-meal threshold matters more with age, and why eating less protein as you age is a major pitfall.
How should I train around arthritis or a joint limitation?
Train around the limitation rather than skipping strength work entirely — improve muscle health in unaffected areas to generate systemic myokine benefit that supports whole-body health. Consult a physical therapist for individualized guidance. Never abandon strength assessment because of a limitation; adapt the movements and continue applying progressive overload where you safely can.
What is the protein threshold and why does spreading protein fail?
The protein threshold is the minimum blood amino acid concentration needed to trigger meaningful muscle protein synthesis — roughly 25–30 g of protein per meal in older adults. Distributing small amounts throughout the day may never reach that threshold at any single sitting, rendering much of the total intake useless for building muscle. Total daily grams mean nothing if each dose is too small.
