This episode features Dr. Stephanie Estima, a chiropractor and author with 20 years of clinical experience, who argues that women have been systematically given bad health and fitness advice centered on “getting smaller” at the expense of muscle, bone density, hormonal health, and long-term wellbeing. Her mission is to shift women’s focus from losing (weight, inches) to gaining (strength, bone density, mobility, body confidence), drawing on both her clinical work with tens of thousands of patients and her own painful experience with extreme figure-competition dieting, which left her at 11% body fat, without her period, and hating herself despite external compliments.
The Four Female Fitness Archetypes
Dr. Estima identifies four archetypes women cycle through on their fitness journeys, with the goal of reaching “Dialed-In Diana”:
Overwhelmed Olivia: Paralyzed by conflicting online information (plants are toxic vs. plants are great, light weights vs. heavy weights), she fears failure and does nothing. The fix is quick wins — like walking 5,000–7,000 steps a day — to build confidence before layering in more.
Skinny Fat Sophie (TOFI — Thin on the Outside, Fat on the Inside): Not obese but losing muscle and bone, she fears heavy weights and restricts calories. She does Pilates, yoga, and walking. When she starts eating more and lifting heavier weights, she’s shocked to discover she loses fat while eating more — the most common patient Dr. Estima sees.
Exorcist Emily: Works out intensely (she’s the woman crushing it at the squat rack with headphones on) but still under-eats because she’s afraid of gaining weight. There’s a mismatch between her high exercise output and insufficient food intake. Dr. Estima was this archetype during her divorce, using the gym to punish herself while grieving.
Dialed-In Diana: The target archetype. She enjoys movement, fuels her body to nourish her lifts and recovery, eats for pleasure as well as function, and gives herself grace with recovery. Women can oscillate between archetypes, which is normal.
Five Fitness Myths Debunked
Myth 1 — Carbs make you fat: Low-carb or keto diets can be useful temporarily for specific populations (e.g., type 2 diabetes, PCOS) to improve insulin sensitivity and glucose disposal, but staying there too long can impair thyroid function, causing cold hands, heavy menstrual bleeding, hair shedding, and loss of the outer third of the eyebrow. Women need carbs for mood, sleep, and gym performance. The real issue is overconsumption of total calories, not carbs specifically. The carbohydrate-insulin model of obesity has largely been discredited.
Myth 2 — Lifting heavy makes women bulky: 97–98% of women lack the hormonal environment (testosterone levels roughly 10–20× lower than men) to bulk like bodybuilders. The analogy: driving to the store doesn’t make you a Formula 1 driver. Initial “bulk” some women feel is just muscle swelling and inflammation underneath a fat layer.
Myth 3 — Long fasting is ideal for women: Extended fasts (20–72 hours) signal famine conditions to the ovaries, which have ~100,000 mitochondria per oocyte constantly scanning for safety. This can shut down the menstrual cycle to prevent pregnancy during perceived food scarcity. A safer approach: stop eating 2–3 hours before bed, sleep 8–9 hours (giving a ~10–11 hour fast), then eat in the morning. Pushing the eating window later makes it harder to get sufficient calories and protein.
Myth 4 — Post-workout meal timing is critical: The idea that you must eat within 15–30 minutes after training is largely false. Muscle protein synthesis continues for 10–72 hours post-workout. What matters is total daily protein and calories, not immediate post-workout fueling.
On pre-workout fueling: Ideally eat a small amount of protein and carbs before training, but Dr. Estima personally trains fasted on weekday mornings and uses ketone supplements (she co-owns a ketone company) for neural drive during big muscle-group days. Weekend training is fueled with real food, which always improves her performance.
Myth 5 — (Implied envelope of myths discussed throughout): Additional myths addressed include the fear of cortisol spikes (normal and necessary — you need cortisol to wake up and to train with intensity) and the idea that running is bad for your knees (“use it or lose it” applies).
Training Principles for Women
Strength training should be the foundation: Aim for 3–4 days per week, alternating upper and lower body. For each target muscle group, aim for ~10 sets per week. You don’t need to train to absolute failure — working within 1–3 reps of failure (RIR) is sufficient.
Five muscle groups to prioritize for an hourglass figure (from her upcoming book Nothing to Lose):
Lats (back): Called “angel wings” — widening the back creates the appearance of a slimmer waist.
Glutes (max, med, min): Critical for curves and for stabilizing the spine, knees, and ankles.
Adductors (inner thighs): Help stabilize during falls and contribute to leg shape.
Pelvic floor / core: Essential for women, especially mothers.
Women’s anatomy requires different movement cues than men’s:
The female pelvis is wider and more shallow (heart-shaped vs. oval), creating a larger Q angle — the femur angles more medially, making women more “knock-kneed.”
This increases shear forces on the knee (especially the ACL) and means women often benefit from a wider squat stance with toes turned out.
The gluteus medius is especially important for women to control femoral inward rotation and protect the knee.
Women are more prone to ACL injuries when fatigued; deceleration and change-of-direction training are more predictive of elite athletic performance than vertical jump or sprint speed.
Sprinting is critical at any age: VO2 max declines ~10% per decade if untrained, and muscle declines ~1% per year. A study of postmenopausal women (average age 58) doing sprint interval training for 8 weeks increased VO2 max by 10%, with mitochondrial efficiency improvements of 69% (vs. 49% in 18–30-year-olds). The Norwegian 4×4 protocol: 4 minutes at 85–95% max heart rate, 3-minute rest, repeated 4 times.
Jumping and deceleration training: Essential for bone density (strain magnitude and strain rate drive bone reformation) and fall prevention. Even isometric holds (e.g., standing on toes to load the Achilles) can progress to hops and jumps.
Connective tissue (joints, tendons, ligaments): The “forgotten” tissue. Muscle gets the attention, but you can’t squat without healthy knees. Strengthen tendons and ligaments by emphasizing the eccentric (stretching-under-load) portion of lifts. Collagen supplementation (10–15g/day of hydrolyzed type 1, 2, and 3) supports joints, tendons, ligaments, fascia, skin, hair, and nails — though it’s a poor muscle protein source due to low leucine.
Nutrition and Supplementation
Protein: Dr. Estima gets most protein from whole foods and uses protein shakes mainly when traveling.
Creatine: 3–5g daily for all women (not just “bros”). It enhances performance and strength when paired with resistance training. A perimenopausal hack: 10g on poor-sleep days helps cognition and alertness, as higher doses may be needed to cross the blood-brain barrier.
Magnesium glycinate: 250mg at lunch and evening for relaxation, sleep, and muscle recovery. She habit-stacks by keeping it next to salt and pepper at lunch and in her bathroom for bedtime.
Omega-3s: 2–4g/day for inflammation and cognition. Keep in the fridge and place next to frequently reached-for foods.
Vitamin D3 + K2: Minimum 4,000 IU/day. It’s actually a prohormone important for sex hormone production, inflammation, and cognition. Deficiency is common even in sunny climates.
Collagen: 10–15g/day (hydrolyzed types 1, 2, 3), ideally with vitamin C to enhance absorption.
Electrolytes: Useful on heavy sweating days (e.g., tennis in heat). As women lose estrogen in midlife, salt regulation declines.
Zone 2 cardio and HIIT/SIT: Both benefit women with PCOS or insulin resistance. Muscle contraction helps pull glucose into cells regardless of insulin. Sprint interval training (SIT) — 10–20 seconds all-out, repeated 4–6 times — improves glucose disposal capacity over time.
Pelvic Floor and Mother-Specific Considerations
The pelvic floor is a sling of muscles (pubococcygeals) from pubic bone to coccyx that holds organs in place. Women have three openings (urethra, vagina, anus) vs. one for men, making mechanical support harder. Pregnancy, relaxin hormone, the weight of the baby, and birth further compromise pelvic floor function.
After childbirth, get clearance from your OBGYN before returning to heavy loads. Kegels help weak pelvic floors but can make a tight pelvic floor worse. A pelvic floor physiotherapist can properly diagnose and treat.
Dr. Estima included a chapter on sex in her book The Betty Body because many women silently suffer from pain during intercourse (often related to pelvic floor dysfunction or low back pain) and feel they can’t talk about it. One patient came in for “mechanical low back pain” but privately revealed she couldn’t be on top of her husband without pain — and after treatment, she could.
Hormones, GLP-1s, and Recovery
Hormone replacement therapy (MHT): Helps with sleep, mood, and hot flashes/night sweats, but it won’t lift weights for you, build a healthy plate, or set boundaries at work. It should be combined with lifestyle medicine (training, nutrition, stress management, recovery), not treated as a standalone solution.
GLP-1s: Acknowledged as interesting but discussed in the context of a broader tendency to focus on benefits while divorcing ourselves from potential side effects.
Recovery priorities:
Sleep (S-tier): Growth hormone and IGF-1 surge during sleep; muscles grow and the brain cleans itself. The #1 priority, though challenging in perimenopause.
Sauna: Called “lazy cardio.” Finnish sauna studies show significant health benefits. (Sauna is the only English word borrowed from Finnish.)
Electrolytes: For replenishment after heavy sweating.
Personal Reflections
Dr. Estima competed in a figure competition at 11% body fat (women’s essential fat is ~10–13%; healthy range is ~18–25%). She lost her period for 2–3 months before the show, gained all the weight back, and felt like a failure — despite being showered with compliments while starving, overworked, and not menstruating. This experience drove her career shift.
At 48 (nearly 50), she feels she inhabits her body in a way she didn’t in her 20s or 30s. Weight training taught her to love herself, be patient with herself, forgive herself, and reimagine her relationship with failure.
She believes in God as a force greater than us that presents the same lessons until we’re willing to learn them. A successful life, for her, means her family and grandchildren surround her, carrying forward the values she passed on — leaving the world better than she found it.
Her message to women: “You’re not behind. You are absolutely enough. Don’t be so hard on yourself.”
