In this episode of Huberman Lab, featuring Dr. Lauren Colenso-Semple and Andrew Huberman, The Most Effective Weight Training, Cardio & Nutrition for Women | Dr. Lauren Colenso-Semple explores women’s training basics: progressive strength, smart cardio, ignore hype cycles Dr. Lauren Colenso-Semple argues that skeletal muscle biology and training adaptations are largely similar in men and women; differences in baseline muscularity are mainly driven by puberty-related testosterone, not different “rules” for women’s training.
Women’s training basics: progressive strength, smart cardio, ignore hype cycles
Dr. Lauren Colenso-Semple argues that skeletal muscle biology and training adaptations are largely similar in men and women; differences in baseline muscularity are mainly driven by puberty-related testosterone, not different “rules” for women’s training.
She outlines practical resistance-training setups (2–3x/week full-body or higher-frequency splits), emphasizing progressive overload, sufficient volume, and training close to failure rather than chasing gimmicks like hormone “boosting” workouts or extreme tempo tricks.
On cardio, she explains the interference effect is usually only relevant with very high endurance volumes placed too close to strength sessions; for general health, enjoyable activity plus strength training often suffices.
She tackles popular misconceptions—cycle syncing, cortisol fears, fasted training myths, and exaggerated hormone-therapy/creatine claims—while highlighting the importance of consistency, technique, and individualized decision-making based on how you feel.
Key Takeaways
Women and men build muscle similarly once training starts.
Baseline muscle mass differs largely due to male puberty testosterone, but relative hypertrophy responses to training and protein intake are very similar across sexes.

Train close to failure; “easy sets” don’t drive much growth.
A workable heuristic is stopping ~1–2 reps shy of true failure; if you can do another 10 reps, the load is too light for hypertrophy.

For beginners, 2–3 full-body sessions/week is a high-return default.
Full-body training hits major muscle groups frequently enough without complex splits; if training 4+ days/week, upper/lower or push–pull–legs becomes practical.

Do 2–4 hard work sets per exercise/muscle focus—usually 3 is the sweet spot.
Colenso-Semple prefers ~3 work sets after warm-ups; beyond ~4 tends to be unnecessary for most people, especially when compound lifts already hit multiple muscles.

Rest is best individualized; ~2 minutes works for most, longer for heavy compounds.
Use auto-regulated rest: ~2 minutes is often enough for machines/dumbbells; ~3 minutes for squats/deadlifts; ~4–5 minutes if maximizing 1RM strength.

Rep ranges are flexible for hypertrophy; volume and effort matter more.
Muscle can grow with low or high reps if sets are near failure, but very low reps require many more sets to match volume; a common practical range is ~6–12 (beginners ~8–12).

Menstrual cycle ‘phase-based’ training changes aren’t supported by evidence.
Rather than overhauling training by cycle phase, train consistently and adjust only when symptoms meaningfully affect readiness (swap exercises, reduce load, or skip if needed).

Oral contraceptives generally don’t meaningfully change strength or hypertrophy adaptations.
Most data on combined oral contraceptives show no meaningful effect on performance or training adaptations; side effects may affect short-term willingness to train, not physiology of adaptation per se.

Menopause doesn’t require a new training philosophy—strength training becomes more important, not different.
Menopause itself doesn’t appear to uniquely accelerate lean-mass loss; inactivity does. ...

Fasted vs fed training is mostly preference for typical lifting; it doesn’t drive superior fat loss.
Longer-term studies show similar muscle/fat outcomes; “fasted fat burn” doesn’t translate to meaningful long-term fat loss differences, and pre-lift meals often aren’t used as immediate fuel anyway.

Protein timing is less critical than daily consistency.
The post-lifting muscle-protein-synthesis window is long (still elevated many hours later), so hitting total daily protein reliably matters more than a narrow ‘anabolic window’.

Creatine monohydrate (powder) is the evidence-based choice; gummies can be unreliable.
Typical dosing is ~5 g/day for exercisers; some gummy products have tested as under-dosed. ...

Cortisol is being misused as a scare tactic; normal exercise-related spikes don’t cause ‘belly fat.’

If you ‘speed up recovery’ too much, you may blunt adaptation.
Ice baths and NSAIDs can reduce soreness/inflammation but may interfere with hypertrophy signaling—recovery tools should match goals and timing.

as a woman, if I honestly thought there were things we should do differently to optimize our results, of course, I would be doing them myself and telling other women to do them, too. The narrative that women need a sex-specific program or nutrient timing guidance or a particular intensity of exercise or rep range or all of it, it makes women feel like they're being spoken to and being considered, and they're, and they're part of this community, instead of, "Oh, you know, just do what your boyfriend does or what your husband does," or... So the narrative is very much women are not men, and so obviously women need something different. The data says men and women respond to exercise very similarly. [upbeat music]
Welcome to the Huberman Lab Podcast, where we discuss science and science-based tools for everyday life. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. My guest today is Dr. Lauren Colenso-Semple. She holds a PhD in integrative physiology and is a certified strength and conditioning specialist. She is an expert in both the science and practice of building muscle and strength, cardiovascular fitness, and the relationship between hormones and exercise. Today's discussion is focused on fitness for women and how it overlaps directly with the same things that men should do for their fitness. Therefore, today's discussion is relevant to both women and men. Dr. Colenso-Semple explains how to structure your ideal training routine according to the time you have available and your health and fitness goals. She also clearly explains what the science says about if and when women's hormone cycles, life stages, such as menopause, and things like birth control should actually impact how women should train and when. As we all know, information about best practices for fitness, nutrition, and health are hotly debated online. Dr. Colenso-Semple has become one of the most trusted voices for explaining what the science says about women-specific fitness, as well as for delivering clear, actionable evidence for protocols that work in the real world. It was a true honor and pleasure to host her on the podcast. Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford. It is, however, part of my desire and effort to bring zero cost to consumer information about science and science-related tools to the general public. In keeping with that theme, today's episode does include sponsors. And now for my discussion with Dr. Lauren Colenso-Semple. Dr. Lauren Colenso-Semple, welcome.
Thank you.
Very excited to have you here. To kick things off, is there anything fundamentally different about muscle tissue in men and women? And if not at the cellular level, in terms of the hormone receptors that they express or the hormones that they're exposed to, in a way that should change people's behavior about how to exercise.
When we look at how the muscle responds, so we look at muscle protein synthesis in response to exercise or nutrition, there are no differences. Very similar protein metabolism response, very similar growth response. The major difference, and this is hormone-related, i- is, uh, the baseline muscularity, because during puberty, when men experience a surge in testosterone, that coincides with an increase in muscle mass. So if you take an untrained adult man and an untrained adult woman, there will be a disparity in their baseline muscle mass, and that is due to differences in testosterone. However, once they start training, they will gain similar relative size.
