The story goes that hard exercise is risky for women, and that the idea is ancient. Both halves fall apart on contact. In this solo episode, Dr. Jordan Feigenbaum follows the claim that physical effort harms the female body across twenty centuries, and shows that almost every version of it arrived as a verdict first, with the science bolted on afterward. It runs from antiquity to the present: what Galen actually wrote, why Sparta trained its women on purpose, the Victorian “vital force” panic an...

In 1889 a French physiologist injected himself with guinea pig and dog testicle extract and published a claim of self-rejuvenation in The Lancet. That announcement kicked off a 200-year medicalization of menopause that ran through leeches and bromides, Premarin, the 2002 Women's Health Initiative, and the contemporary menopause-content space. In Episode 1 of our three-part menopause series, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through what menopause actually is at the hormonal level,...

This is the free preview of the May 2026 Direct Line, our monthly AMA for Barbell Medicine Plus subscribers. Three reader questions answered in full. We open with a mid-30s woman with bilateral shin pain and exertional foot numbness who started creatine a month ago and is asking whether the supplement is the cause. We walk through the compartment syndrome literature, the 2025 case report being passed around online and misinterpreted, what creatine actually does to total body water (and what it d...

Most cases of low testosterone in modern men are not a problem with the testes. The number is downstream of body composition, sleep, and energy availability. The wellness-clinic algorithm walks past every one of them. Jordan and Austin walk through what actually drives men’s testosterone down, the mechanisms behind it, and the modifiable levers that bring it back up. MOSH, the leptin and Kisspeptin pathway, the aromatase loop, the sleep apnea picture most clinics never ask about, the GLP-1 and w...

Three weeks of stalled squats. The conventional answer is to switch programs because you've crossed into intermediate territory. The data says something else. In Part 3 of the Progressive Loading series, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through why the standard novice / intermediate / advanced framework runs into trouble in real training, what the four adaptive systems are actually doing across a training career, and why most of what gets called a stall is impatience with the noi...

Out of 32 symptoms commonly attributed to low testosterone, only 3 actually correlate with it. All three are sexual. The other 29 — fatigue, brain fog, low mood, weight you can't lose, feeling not quite like yourself — are real, but they are produced by something else, and the wellness-clinic funnel runs on getting that wrong. Episode 2 of our Signal book launch series. Dr. Jordan Feigenbaum and Dr. Austin Baraki cover how testosterone actually works, what the number on your lab report is really...

Stop a GLP-1 and about two thirds of the weight loss comes back within a year. Three randomized withdrawal trials (SURMOUNT-4, STEP 1 extension, STEP 4) and a new BMJ 2026 systematic review of 37 RCTs and nearly 10,000 adults all land on the same signal. The cardiometabolic benefits, blood pressure, fasting glucose, lipids, drift back in parallel with the weight. The framing that actually fits the data: GLP-1s behave like a statin. There is a cumulative benefit during exposure, but this does not...

Every week there's a new headline saying men are losing testosterone. A quarter of men now start testosterone replacement therapy without ever getting their blood tested. The supplement aisle is full of boosters that either do nothing or contain undisclosed steroids. And the lab test that gets everybody to the pharmacy? Half of low results normalize on their own. In Episode 1 of the Signal launch series, Dr. Jordan Feigenbaum and Dr. Austin Baraki (both MDs and strength coaches) walk through the...

A 43-year-old man starts exercising and ends up in the ER with a CK over 100x the upper limit of normal. His doctor says it’s from training. We don’t think so. In this episode, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through the full case — history, labs, diagnosis, and what actually went wrong — then break down the mechanisms behind the answer, the nocebo research, and what the brand-new 2026 guidelines mean for the 40 million Americans on a drug class you’ve definitely heard of.

In 2022, researchers conducted the most rigorous systematic review ever performed on overtraining syndrome — looking specifically for controlled studies that documented a human transitioning from a healthy training state to an overtrained state. Zero studies met those criteria. The word "overtrained" appears in coaching certifications, wearable device dashboards, and clinical sports medicine guidelines — and in each context it means something different. That definitional chaos has consequences: ...

Feigenbaum and Baraki cover: VO2 max versus cardiorespiratory fitness for longevity (are Peter Attia’s targets evidence-based? — with Goodhart’s Law and the JAMA evidence), what GLP-1 medications actually cost now via manufacturer programs ($149–449/month), and whether 7,000–10,000 daily steps actually meet the bar for cardiovascular training.

You can have a completely normal BMI and be on your way to cardiovascular disease, type 2 diabetes, and metabolic syndrome without triggering a single alert on a standard health screening. The fat that predicts metabolic risk most accurately isn't the fat your scale or your doctor is tracking. Dr. Jordan Feigenbaum breaks down the science of visceral fat — what it is, how it causes disease, how to measure it correctly at home for free, and what the evidence actually shows about exercise, GLP-1 m...

A fit, healthy 39-year-old was nearly sent for a liver biopsy. The cause? Was it that he went to the gym before every blood draw or because his supplement was throwing his labs off?.

We dive into the persistent myth of "muscle imbalances" and why your asymmetry might actually be a functional feature of your training. We also address the "meat" of the cardiovascular debate: is red meat and saturated fat consumption still risky if you are highly active and have a high-fiber diet? Finally, we explore t...

Most doctors, trainers, and "safety-first" influencers warn that holding your breath while lifting is a dangerous habit that could lead to a stroke or heart failure. By looking back at the 300-year history of the Valsalva maneuver—from a 1704 ear treatment to the "boogeyman" blood pressure studies of the 1980s—we dismantle the myth of the "fragile tube." Discover the science of the "pressurized suit" and why your body is actually designed to handle extreme internal pressure during heavy exertion...

The longevity industry is now worth over $100 billion per year. From DNA methylation clocks to multi-cancer blood tests and GLP-1 medications, the promises are bold. But what actually predicts lifespan? In this episode, Dr. Jordan Feigenbaum and Dr. Austin Baraki break down the science behind biological clocks, the real story on GLP-1–related muscle loss, and introduce the Barbell Medicine “Vital Five” — a clinically grounded framework for health and longevity.

Lifting more weight doesn't always mean you've gotten stronger. In this foundational session, Dr. Jordan Feigenbaum and Dr. Austin Baraki introduce the Fitness-Fatigue Model to explain why "stalled" progress is often just a temporary masking of strength by accumulated fatigue. By learning to differentiate between a lack of fitness adaptation and a lack of recovery, you can avoid the "panic pivot" and maintain the long-term signal necessary for elite-level gains.

Dr. Feigenbaum and Dr. Baraki walk through the clinical workup of a 24 year old male presented with persistent weakness in his foot following weight loss of 22 pounds in two weeks. What could've possibly caused this? The discussion pivots to the science of how fast one should lose weight. While athletes should prioritize slow loss to preserve performance and lean mass, the data for individuals with obesity suggests that the speed of loss may be less critical than protein intake and resistance tr...

For decades, the health and fitness industry has blamed rising obesity rates on a lack of individual willpower and "poor choices." However, a landmark lawsuit in San Francisco argues that the modern food environment is a public nuisance engineered by food giants using a literal tobacco playbook. By manipulating "Bliss Points" and dismantling the natural food matrix, these companies have created an environment where healthy choices are the path of highest resistance.

Biohackers and longevity clinics claim peptides are a side-effect-free sniper rifle for fat loss and injury recovery, but the reality is often buried in failed clinical trials and regulatory bans.
