378 ‒ Women’s health & performance: how training, nutrition, & hormones interact across life stages
Peter Attia hosts Abby, a former collegiate distance runner (3K, 5K, 1500, 800) who loves strength training despite endurance goals. Fell in love with science and research: "the more you know, the more you don't know." Bob Kaplan quote: "the further you get from shore, the deeper the water gets."
800 and 1500 are most painful events; 1500 requires two more laps at similar pace to 800.
Exercise delays chronic disease onset and improves healthspan/quality of life. Focus on exercise for women from beginning of life cycle.
Osteoporosis as a childhood disease: Women reach genetic peak bone density ~age 19, then maintain it lifelong; menopause erodes it.
Recommendations for 10-Year-Old Girls
- Exercise as play, transitioning to varied types.
- Build early fitness base: easier to maintain over time.
- Literature supports early start.
Menstruation turning point: Girls often leave sports due to body changes, performance differences.
Abby's lab researches menstrual cycle impacts on performance, recovery, bloating, mental health.
No one talked about menstruation when Abby was growing up.
Abby played all sports; grew up with "exercise more and eat less." Running and resistance training empowering as fitness/strength visibly improves.
Lack of education: menstruation healthy; in sports, no period seen as badge of honor; tied to nutrition.
For sports like field hockey, volleyball, basketball:
- Avoid specializing; play varied sports to accelerate diverse muscles/movements.
- Resistance training best for injury prevention; often neglected by coaches.
- Total body exercises: resistance bands, light weights, plyometrics, medicine balls.
Abby's favorite lift at 11-12: Romanian deadlift.
Common in gymnasts, runners; also swimmers (high volume), cyclists.
Downsides:
- Negatively impacts bone health due to delayed estrogen onset.
- Often tied to caloric restriction or overexercise (not always intentional).
- Track/field, gymnastics athletes show spinal curves (not full scoliosis) on DEXA scans; every high jumper/gymnast affected.
- Pole vaulters too (asymmetric loading).
UNCC (15 years): DEXA whole-body scans for body comp reveal this.
Stabilize as you age via musculoskeletal work; can't fully reverse at 18-19-20.
Males: Less seen (no male gymnastics team); hypotheses - more spinal musculature, puberty timing.
No strict ceiling when young; body highly responsive to training adaptations.
Example: Abby did cross country to get in shape for basketball; different energy systems, but overall fitter by end.
Exercise yields improvements at any age; sets habits, shows physiological adaptations.
Key for skeleton and habits: you're in control.
Nutrition as fuel: Prioritize adequate calories.
Nutrient timing: Leverage pre/during/after training (especially when busy).
For young female athletes:
- Increased GI distress; hard to exercise on full stomach.
- Educate on nutrients for better performance/recovery vs. specific foods to eat/avoid.
Morning practice issue (e.g., cross country): Not hungry, minimal eating (bagel bite), then school.
Strategies:
- Higher quality/essential fats for caloric density with less volume: higher fat milk/yogurt, nuts, seeds.
- Small swaps: whole milk vs. skim.
- Packable foods.
- Plan eating: exercise blunts intuitive hunger; GI distress common in girls/women.
GI distress causes: Whole GI tract; stress-induced; aligns with menstrual cycle (worse pre-menstruation, beyond cramping).
Carbs essential for active individuals, especially young females; shift away from protein-centric advice.
Can train any cycle phase; data shows performance maintained.
Feel worse in phases (esp. luteal phase pre-menstruation): fatigue, bloating, slower recovery/soreness.
Physiological response; coaches may dismiss ("you're fine").
Olympics: Women compete regardless (even one-shot events); key difference in recovery for repeated events (inflammation, protein breakdown varies by phase).
Cycle Phases and Strategies (Traditional Cycle; Individual Variation High)
Use at-home monitoring tools for personalization (e.g., bleed 3 days, non-textbook hormones).
Early Follicular (Days 0-5: Period, Low Hormones - FSH, LH, Estradiol Low)
- Greater carbohydrate oxidation; feel/perform better.
- Steady; do normal training, fuel with carbs.
- Hydration key (menstrual fluid loss).
- Iron: Transient loss minor; not major via fluid alone.
- Blood loss volume highly variable; unclear correlation to exercise intensity (individual genetics/physiology).
- Endurance: Noticeable oxygen capacity loss.
- Eat regularly; match to intensity/volume; slightly more carbs.
Late Follicular (Days 7-14: FSH/Estradiol Rise, Towards Ovulation)
- Feel best; most fertile.
- Peak performance feels easier; optimize volume, quality, sleep, recovery.
- Ideal for testing peak performance.
Ovulation/Early Luteal
- Some women sense ovulation (lasts days); variability (may bleed without ovulating).
- Treat like prior week; not difficult yet (progesterone rising slowly, no crash).
Late Luteal (Progesterone Peak/Crash + Estradiol Drop)
- Emotional: Anxiety, depression (individual; ? CNS progesterone receptor density).
- Physiological: Thermoregulation changes, fluid retention, greater inflammation.
Strategies (prepare pre-crash: prioritize sleep, target inflammation):
- For severe symptoms (anxiety/depression, fluid retention, painful periods):
- Omega-3: 2-3g to downregulate inflammation.
- Zinc, magnesium: Aid vasodilation, sleep (luteal sleep often down).
- Increase fruits/vegetables for inflammation.
In the luteal phase progesterone rise, data suggests increased protein turnover and protein breakdown, along with edema. Creatine pulls water into cells, helping shift extracellular fluid intracellularly, supporting performance in follicular vs. luteal phase. Caffeine may be more helpful in luteal phase for fatigue. Strategies can optimize this phase.
Omega-3s at higher doses might be pulsed based on cycle, but magnesium is critical throughout. Creatine is valuable daily.
If a woman didn't want to manage by cycle: enjoy caffeine (more benefit in luteal), creatine reduces bloating by pulling water into cells.
Creatine dosing in women: Lab studies (including first on creatine and perimenopause) use loading to accelerate saturation: 20g/day for 5 days (split into four 5g doses), then 5g/day maintenance. Data supports up to 10g/day for midlife women or brain health. Steady state without loading takes weeks. Recent shift to 10g/day maintenance post-discussion with Rhonda Patrick.
Women report reduced luteal phase edema with creatine.
Luteal Phase Metabolic Changes and Protein Synthesis
Luteal phase shows increased metabolic rate (~200-300 calories/day energy expenditure), possibly due to temperature, uterine lining, or progesterone. Women feel worst then (fatigue, cravings), retain water (scale up), under-eat despite needs—perfect storm for under-consumption.
Protein synthesis across cycle (paper in review, young women): adequate protein (~1.6g/kg) mitigates issues; nutrient timing around workouts optimizes. Target 2g/kg as buffer to hit 1.6g minimum. Consistency and timing key (e.g., protein every 5 hours).
Anecdote: Host struggled on Asia trip (low volume/intensity, ~1.2-2g/kg, no snacks), but short-term lapses tolerable with consistent exercise base. Constant travelers need attention.
For vegetarians/aging muscle (40s-50s, anabolic resistance, hormonal shifts): pay extra attention post-ovulation (early luteal) for MPS, soreness, recovery, injury prevention.
Periodize intensity/volume on longer mesocycles (peaking/tapering for events), not monthly cycle—accept training suboptimal some phases. Align 4-week mesocycles with period possible (research needed). Train consistently for long-term effects; give grace for off days (hormones, recovery). Track cycle (bleeding length, tiredness) to empower vs. self-blame.
Consistency matters; empower women to track hormones/bleeding/mental health changes (not taught), distinguish hormonal vs. other issues.
Oral contraceptives (no placebo week, suppress ovulation): indirect performance advantage via consistency, less variability, symptom relief (mood/cramps), no bleeding.
Symptom-driven; start bloodwork in 30s. Day 5 FSH (day 1 = period start): low when fertile, hits 10+ entering perimenopause, 25-50+ in menopause. AMH helpful. IUDs complicate (may breakthrough bleed 3x/year).
At-home urine tests (daily): estrogen, progesterone, FSH, LH (devices vary; not as accurate as blood but show daily variation, spikes/drops correlating to symptoms like sleep/hot flashes). Correlate with blood.
Studies (follow-up to SWAN studies, sophisticated metabolism/body comp): perimenopause shows significant changes in metabolism, muscle size/quality, bone, metabolic flexibility—more stable post-menopause. Target late 30s-50s for lifestyle changes to improve healthspan.
For busy mom (3 kids <6, low exercise): never too late; consistency > 150 min/week. Intensity > volume; prioritize to combat mom guilt—benefits family (keep up with kids, better mom/wife). Tie to longevity/quality of life.
Host: Wife more selfless (defers workouts); women wired that way.
Volume vs. Intensity Debate
Literature: unlimited time, volume matters most; limited time (e.g., 150 min/week), prioritize intensity. Pros (25+ hrs/week) do 80% low-intensity volume. For low-volume (e.g., 3 hrs/week total), mostly high-intensity maximizes effect (but misses base-building).
Intensity matters always; exercise snacks (high-intensity short bursts) for VO2 max gains (faster than volume, less daunting for beginners). Scott Trappe's work: elite endurance athletes—volume good for capillarization/blood flow, but doesn't maintain muscle size/quality.
3 hrs/week structure (midlife woman, general goals): prioritize 2 days/week whole-body progressive resistance training (higher intensity; studies fit into 2 days), 2-3 days aerobic exercise.
They recommend a little higher intensity progressive resistance training and 2-3 days of aerobic exercise, hopefully two of those high intensity. It depends on goals: lose fat, gain muscle, or just move. Need a blend of consistent resistance training and heart rate elevating exercise vs. just low-moderate intensity.
Sample Weekly Structure
- 2x 45-minute (or 30-minute for efficiency) whole body resistance days.
- Resistance protocol: 6-8 reps at 60-80% 1RM, 30 seconds between exercises, 2 minutes between sets; totals 30 minutes (1 hour/week).
- Remaining 2 hours for cardio (treadmill, bike): at minimum 1 day/week high-intensity interval training (HIIT), ideally 2 for bigger benefits; value in movement like walking or low-intensity bike for blood flow and heart rate elevation.
HIIT Structure
- Effective protocol for fit to cancer patients: 10 sets of 1 minute on / 1 minute off at 90-110% VO2 max (pick intensity where 1 minute is really hard, can't sustain 1:20).
- Alternatives: measure VO2 max precisely or max heart rate; or just "go hard for 1 minute needing a break."
- Heart rate issues for short intervals: heart doesn't reach max until end; at start of interval, HR might drop (e.g., from high to 100 bpm if max 180), causing confusion—teach RPE (rate of perceived exertion).
- On bike/treadmill/ergometer, lock in power/speed to force effort.
- Benefits even if not hitting 90%; can do at home; learn high-intensity feel; PE/HR varies daily.
- Start with 6 sets, up to 10; 1 min on/off feasible solo; 10 min work / 20 min total; great for busy schedules (e.g., 6 intervals before kids' baseball).
Allocating 3 Hours/Week (1 Hour Resistance + 2 Hours Cardio)
- 2x HIIT (30 min each with warmup/cooldown = 1 hour total).
- Remaining 1 hour: 1-2 low-intensity days, or daily movement for consistency (speaker needs exercise daily to feel well).
- Prioritize 2x HIIT over extra LISS; increases lean mass helpful for midlife.
Differentiate: women say "weigh less," avoid knowing body fat; weight may not change or increase with recomp. Educate on body composition.
Counseling for "I Want to Lose Weight" (Means Lose Fat)
- Measure: DEXA, multi-frequency bioelectrical impedance, or at-home scale for tracking.
- Calculate ideal weight from % fat/muscle; set goals for % fat/muscle based on health/weight aims (e.g., high school weight may require muscle loss).
- Ideal body fat: Use NHANES normative data; ~50th percentile shows cardiometabolic changes (aim 25th percentile or lower).
- Example: 40yo, 5'6", 150 lbs, 30% BF (~30-50th percentile NHANES).
- Goal: lose 20 lbs to 130? Assess composition (bone, lean soft tissue/muscle, fat storage); typical 40yo mom: hips (younger), shifting abdominal (not always visceral) with age, increasing cardiometabolic risk.
- If visceral low, metabolically healthy, subcutaneous fat: 20 lbs too much; aim ~10 lbs to 140 lbs based on skeleton; follow-up measurements.
- Strategies: hypocaloric intake (slight deficit); track intake; add fiber/protein/complex carbs for satiety (not just remove food); balance with workouts.
GLP-1 Agonists (e.g., Semaglutide, Tirzepatide/Mounjaro)
- For 20 lb loss (150→130), preserve muscle: aim ≤5 lbs muscle loss, ≥15 lbs fat (e.g., 35%→20-22% BF).
- Strategies:
- Prioritize resistance training (maintain lean mass, improve muscle quality).
- Protein: 30g evenly spaced (130-150g/day based on goal weight; higher thermic effect).
- Essential amino acids (EAAs) around exercise.
- Nutrient timing: amino acids pre/post workout.
- New diet: lower calories, higher quality (impacts appetite); many not counseled properly.
- Risks: accelerated muscle/bone loss (measure composition); BMD drop theory: underfueling + perimenopause = relative energy deficiency syndrome (RED-S); mimics hormonal changes (fatigue, low progesterone/estrogen) from calories, not just ovaries.
Minimal changes: prioritize resistance despite low energy (may reduce volume/intensity).
- HIIT stimulates muscle + vascular improvements.
- Options: 2x 30-min strength + 1x HIIT + 1x LISS; or 3x resistance (drop 1 LISS), 1x HIIT + 1x LISS if unfit.
- Gym days: whole body or major groups 2x/week (push-pull); adjust for energy/soreness.
- Sustainable: 24 weeks; body part splits (leg/upper x2); long-term (e.g., 1 year) low-dose tirzepatide (2.5-5 mg), titrate based on lean mass.
Measures every 6-9 months (college through now).
- Distance runner: 9 stress fractures when BF <15% (5'6", ~115-120 lbs); amenorrheic most career.
- Amenorrhea indicates not eating enough/exercising too much; catch before full loss (fluctuations ok, not year without period).
- Bone density high on DEXA despite fractures (fueling/nutrient timing issue, not low BMD).
- Grad school: mentors added nutrition; early work on creatine, beta-alanine; self-experimented (less training time via intensity/volume).
- Did physique show early career to push envelope/science.
- Post-2 kids: measured changes; science matters.
- College running + weight room (loved lifting).
My bone is very high... it very much was a fueling nutrient timing.
They were lifting and running. BMD on DEXA was normal, but stress fractures occurred. Something missing due to activity type. In weight room, getting appropriate deformation. Muscle quality issue, more catabolic protein breakdown.
Stress fractures all in left leg and foot, inside leg on track. D2 athlete: cross country, indoor track, outdoor track. Repetitive strain. Happened twice during race, finished but couldn't walk afterward. Love to push hard, sometimes too much. Training intensity, volume, specificity, and nutrition interplay; can't do one without others.
Doesn't remember protein amount then. Early underconsumption sign: worst GI distress, colonoscopy. Couldn't have big meal before 1000m repeats on track. Extended periods without eating, long gaps between meals. Not total amount, but timing around training. Protein and carbohydrates lacking around training. Trained twice a day every day: morning, class, afternoon train, meetings. Long gaps without fuel vs. more frequent consumption.
Grad School Training and Nutrient Timing
Continued running in grad school, thought had to train all the time. Learned didn't have to train as much. Keys of nutrient timing, optimizing nutrition, dietary supplements.
Staple supplements besides creatine: whey protein, amino acids (same as whey, but faster absorption, no milky substance), omega-3, vitamin D, magnesium, multivitamin, probiotic (multistrain based on GI system).
~8% increase in body fat through both pregnancies (depending on measurement). Couldn't tell lean mass components clearly, but didn't lose muscle, gained fat. Measured ~3 months postpartum, took ~6 months to return to normal.
Don't have to exercise crazy postpartum. Finding time to train. Same % body fat and muscle changed depending on training for last 15-20 years after grad school optimization. Students say "not fair, you have science on your side," but consistency, some high intensity, appropriate nutrition means no new set point.
Youngest child is 8 years old (8 years post-second pregnancy). Body composition today approximately same as prior to first child birth—not just weight, actual body composition. Biggest change: periodize—sometimes leaner or not as part of training, not very different.
Gained lean muscle recently, countering midlife message "can't gain mass or losing muscle mass." If training aerobic, maybe lost little muscle. Diet sometimes locked in, sometimes not with travel. Prioritize when wanting leaner: acting more (more whole foods, eating consistently throughout day). Less attention: gain some fat mass.
Eating Patterns for Leanness
Leaner when eating more volume and frequency: ~30g protein + fiber/veggies evenly throughout day stimulates metabolism, more macros/micronutrients.
Vs. chronic time-restriction (wake up no breakfast, eat at 11, snack—not nutrient dense). Lowers metabolism, aftermath on hunger hormones (can't stop eating), impacts protein synthesis, metabolic rate, muscle loss. Especially midlife, pay more attention to food consumption.
Time/place for time-restriction, but many women chronically doing it.
Returned to pre-pregnancy body comp within 6 months while breastfeeding. Approached pregnancy like training for athletic event (birth). Exercised consistently, slowly increased calories like refeed (caloric surplus). Postpartum: hard to nurse/feed self, but back to normal calorie balance. Nursing helps + consistent exercise + calorie play for metabolic changes.
Third Trimester Exercise
First pregnancy: some running, but resistance training priority. Squats, lats—muscles for delivery. Up to day of delivery. Not high intensity, but optimize blood flow, muscle fatigue for birth.
Postpartum Return to Exercise
Two natural deliveries. Walking within couple days, resistance training (lightweight) within couple weeks, running within few weeks (nothing crazy). Benefit of being active.
Pregnancy Cravings and Nutrition
Didn't want animal proteins or protein shakes. Prioritized plant-based proteins (tasted better). Craved donuts (not typical refined carb eater), included them. Intentional consistent eating for caloric surplus, didn't track macros.
Post-children: GI distress (lactose intolerance?). Ate liquid foods (carrying child). Integrated protein shakes, big omega-3, creatine to maintain when not eating full meals.
Biggest Mistakes in Pregnancy/Postpartum
Nutrition: extremes—eat whatever or ignore. Key priority for baby neural development, gut health (fruits/veggies variety).
Exercise: birth athletic event, exercise if never done, continue if always done. Better guidance now than 8-10 years ago.
Postpartum: incorporate exercise despite mom guilt, nursing, hydration, sleep deprivation. Moms go without sleep. Exercise impacts blood flow.
Women disproportionately suffer sarcopenia vs. men: less muscle mass genetically, less likely resistance training.
Data (Bill Kramer paper): ~1 in 5 women (19%) participate in resistance training, only 1 day/week (all ages).
Title IX (1972): cohort of women aging with more exercise experience, aging differently.
Hormone changes impact sarcopenia: oxidative stress, inflammation, vasodilation changes affect nutrient delivery, blood flow, cardiometabolic health.
Training Adjustments for Menopause
Yes, adjustments needed vs. premenopause. Muscle quality changes in 40s/50s (data lacking there, more postmeno 60s/70s).
2-year longitudinal study: initial comprehensive body comp, strength, nutrition info. Followers had less changes (vs. SWAN data). Maintained muscle size, but significant muscle quality changes (ribeye vs. filet). Measured via ultrasound, pQCT (related to MRI). Australia (Severine Leone) longitudinal: muscle quality changes most in perimenopause.
Marbling location: ? between or within cells. Preprint (Leone group) biopsies (pre/post, ~5 perimenopause). Neuromuscular changes, muscle fiber type data good.
Why matters: intracellular fat → insulin resistance (pathologic); athletes intercell fat maybe in flux (desirable for metabolically flexible muscle oxidizing fat).
Metabolic Flexibility in Perimenopause
Measuring: indirect calorimetry (metabolic flexibility), microdialysis (fat oxidation pre/post exercise, interstitial fatty acids).
Perimenopause: less flexible at moderate intensity.
RQ/RER blend for oxidative metabolism (carb/fat). Mathematical model continuum (Asker Jeukendrup work), not on/off (e.g., RQ 0.85 switch).
Outcomes: % fat vs. carb, grams/min; heart rate-driven low/moderate/high intensity; pre/post, perimeno/post; hormonal concentrations early/late perimeno.
Longitudinal + acute studies inform resistance training/nutrition modulation.
Exercise improves metabolic flexibility. HIIT accelerates lipid/fat oxidation (mostly carb during, post-exercise).
HIIT blunts hormonal impact: stimulates flexibility regardless of hormones/age.
Protein optimizes blood flow post-HIIT, doesn't blunt insulin response (helps flexibility). Not looked at resistance training alone.
Driving inflexibility: oxidative stress, inflammation, insulin sensitivity changes. Phenological age to disentangle age vs. lifestyle vs. hormones.
Lifestyle overcomes hormonal components. MHT (menopause hormone therapy): starting to include users/non-users in studies (controlled research lag). Need combo lifestyle + hormones? Impacts: oxidative stress, arterial stiffness, blood flow?
Optimal Training Portfolio
Exercise potent stimulus, optimize for time constraints (bang for buck).
Protein around training (vs. carb timing, lower GI) optimizes flexibility/insulin sensitivity/protein synthesis. Matters more in 40s/50s with muscle size/quality, cardiometabolic, arterial stiffness, neuromuscular changes—bigger bang for buck.
Most interesting unanswered questions (answerable with resources/will): one of
Women ultimately want to lose weight. Combine GLP-1s with minimal effective dose of exercise and nutrition so women can live their lives and feel good. Many women feel bad on or off these drugs. Exercise plays a key role in mental health.
Increased conversation around menopause hormone therapy (MHT). Indirect effects on muscle and training volume: more energy allows higher volume and intensity, but does it increase injury risk? Tendons change with hormones. Common fear: Achilles tendon tear.
You're less likely to tear your Achilles sitting on the couch.
Giving hormones as part of broader health strategy to increase activity is positive, but doesn't prevent Achilles injury without specific training. Risk can't go to zero, but proper training reduces it significantly (e.g., 80%):
- Strong range of motion in soleus and gastrocnemius.
- Bouncing exercises.
Education and training specificity are key. Clinical trials comparing "business as usual" (pump and burn) vs. smart programs with tissue/tendon pliability work over 15 years are impossible. Rely on common sense and best practices.
GLP-1s enable long-term safe weight loss but at a cost if not careful. Knowledge exists: take advantage of the drug with responsibility (exercise, nutrition). Unlike blood pressure or cholesterol drugs, GLP-1s require "X, Y, Z" integration.
Absolutes like "must lift heavy," "high-intensity training," or "plyometrics" are unhelpful. Doing something is better than nothing. Leverage traditional strength and conditioning research (mostly male-based): female muscle responds similarly for strength and hypertrophy, with modifications for recovery, rest, joint pain.
Empower women to do what they enjoy. Use established rules: change for strength, hypertrophy, fat loss.
To first approximation, results from male studies apply to women for strength and hypertrophy, though differences in detraining, absolute losses.
Women generally have more type 1 fibers, change slightly differently. Neuromuscular aging and motor unit recruitment may vary by sex. Women gain strength/muscle but not to same absolute as men.
Debate on type 2A fiber loss with age: men have more type 2 fibers, bigger area/percentage to lose. Denervation makes fibers hybrid/type 1-like in both sexes, possibly faster in females. Exercise mitigates.
Andy Galpin: hypertrophy of type 2A fibers is sine qua non of aging. Power lost first (peaks in 20s, downhill after), then strength, hypertrophy last.
Fight to preserve power (explosiveness): controlled ways like Keiser machines, jumping, bouncing to recruit fibers. Even more critical for women.
Power matters for health, quality of life, injury prevention.
Tangible example: Stepping off 6-inch curb and misplacing foot—younger people readjust via power; 65-70yo fall on face due to lack of power.
Maintain power in 40s for bigger long-term impact. Women may suffer more falls partly due to this.
Peri/menopausal joint pain (hormones often fix it), central fatigue, brain health/sleep changes. Nuanced training to maintain power despite these.
For 65-70yo woman starting exercise: never too late. Gain strength/muscle at any age by adjusting volume/intensity. Controls healthspan.
Hire a personal trainer initially for form. Find via referrals (e.g., physical therapist), credentials (location-dependent).
Program principles:
- Slightly higher stimulus than current (none).
- Match motivations: group, solo, home (resistance bands), gym (machines, Silver Sneakers), avoid early free weights.
Total body, 3x/week resistance (every other day for recovery), most days aerobic. Focus:
- Glute activation (banded work, leg press) for lower body stability, slip/trip/fall prevention.
- Push-pull every muscle group.
- Leg extension, hamstrings, calves.
- No early lunges.
- Upper body: shoulder joint/deltoids.
Progress to deloaded movements safely, then low resistance carries (dumbbells/kettlebells for core stability, grip, foot reactivity). Love carries, grip strength (functional, not grippers). Include hip thrusts.
Start carries holding light dumbbells while walking. Submaximal efforts: 1 min hold/1 min rest x3 (no failure), or 20 sets 30s on/30s off.
Belinda Beck's Lift More study (Australia): older women learned barbell deadlifts, threw weight around.
Earlier work: massive strength gains in 24 weeks (leg press, bench press; squats possible).
Exercise impacts anxiety, depression, brain fog. Analogy: tames "20 squirrels in my brain."
Women think symptoms unique/abnormal; provide better prescriptions.
Black-and-white rules ("only do this/not that") harmful. Every woman individual; research as toolbox tools. Adapt for injury, goals. Exercise/nutrition not overwhelming—consistency key. Less rules; exercise powerful regardless.
More conversation on injury and recovery (takes longer with age).
High hamstring injuries more in women (post-pregnancy pelvis shift?). Anecdote: Wife ran Boston Marathon ~20 years apart, same times (smarter training), but feels different (less "float"), high hamstring tendonopathies.
ACL injuries in midlife (possibly from youth sports accumulation, activity levels). Interest: muscle-tendon stiffness changes with age/hormones; non-contact (e.g., dog pull).
Hypothesize: age vs. hormones; inflammation differences in perimenopause (estrogen drop), hsCRP marker higher off hormones.
Discussion on whether hormone therapy changes certain physiological responses; uncertainty noted, with suggestion to investigate further.
- Emphasis on providing comprehensive training guidance for women at all life stages.
- Dispel black-and-white myths like "you've got to do this workout" or "you shouldn't do that."
- Guest's lab is one of few studying creatine in women.
- Creatine is beneficial for training but not magic, especially not the first choice for midlife women.
- Expect more literature in the future; stay informed.
- Need more dialogue on physiological and mental aspects of midlife.
- As a man with a daughter, wife, and clinician, guest seeks better ways to discuss hormone-driven issues vs. those overcome through lifestyle, when to seek medical help, and self-advocacy.
- Challenge: Women often invalidated; leverage science and men in conversations.
"I've yet to find a better example of how the medical system has screwed up in the last 25 years than on this issue, both in the magnitude of what it is and just the fact that it's 50% of the population have been hurt by this."
- Modeled analysis shows no greater negative impact.
- Tide is turning, but a generation of women missed the window for hormone therapy due to doctors' reluctance.
- Rachel Rubin (podcast guest) argues against age-based disqualification: A 60-year-old woman 10 years post-menopause is not barred; no evidence links hormone therapy to increased breast cancer rates if beneficial.
- More doctors now willing and competent, though still few.
- Modern tools beyond old MPA (medroxyprogesterone acetate) and CE (conjugated estrogens), which are outdated.
- Podcast provides extensive content on safe, intelligent hormone use: topical vs. variations, when to start specific options.
- Advice: If a doctor says no, find another.
- Situation improving; 5 years ago bleak, in 5 years better.
- Exercise often overlooked in hormone/GLP-1 discussions despite relieving symptoms.
- Lifestyle changes (exercise) can be more powerful than drugs; drugs facilitate changes.
- Hormones provide independent benefits regardless of exercise.
- Accretive benefit from combining both; logical even if unproven in studies.
- Key questions on optimizing training with hormones/exercise, especially resource-constrained scenarios.
- For unlimited time (8-10 hours/week), optimization differs.
- Real-world priority: Consistency over specifics (e.g., 4x4 intervals vs. 1x1s); do what can be done diligently.
- Application matters most.
- Suboptimal stimulus yields suboptimal results.
- With short volume, intensity critical: Can't "phone in" 2x/week 30-minute lifts or cardio.
- High-volume training (e.g., 6 hours/week) allows 1-2 reps in reserve; low-volume demands near-failure.
- Low base: Any stimulus works initially.
- Trained individuals must "crush" limited sessions for benefits.
- Maintenance goal: Avoid extreme intensity every session as we age.
- For early 40s parent/professional (kids 8 and 10), maintenance is realistic and valuable given high baseline fitness.
- Need sufficient stimulus for muscle mass and peak cardiorespiratory fitness.
- Intervals suffice; intensity required but not every workout "crushed."
- Redefine "crushing": Past extreme efforts (vomiting) vs. today's harder-than-most-appreciate work.
- Beginners need to push through pain post-adaptation.
- Teach "good pain"; adapt goals/phases by life stage.
- Train now at 39-40 to reduce future burden.
"This is such a gift to be able to exercise... one thing that I think will never be displaced by a pill... far too many benefits... from exercise."
- Even 6/10 effort valuable.
- Targets narrow group exercising but plateaued (e.g., mistaking zone 1 for zone 2, no effect).
- Understand nuances: Line between zones/outcomes (health vs. performance).
- Empower women with science on training complexity, counter conflicting info.
- Women increasingly recognize resistance training importance; even non-lifters say "I know I should."
- Cultural shift vs. 20 years ago.
- Exciting space to light science, empower cardio + resistance in feasible time.
