Barbell Medicine Podcast

Obesity roughly tripled in about 60 years, and the genes didn't change in that time. So if body weight isn't a willpower problem, what is it? Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through what actually sets your weight: the adoption and twin studies behind the genetics, the "defended range" your biology fights to hold, the food environment that does most of the eating fo...

Once a month we answer Barbell Medicine Plus subscribers’ questions on the Direct Line. This is a free look at June’s episode. We start with GLP-1 drugs and muscle: why DEXA overstates the loss, what resistance training actually does, and whether creatine is worth taking. Then whether bulking and cutting does anything the scale can’t already tell you, how to get real benefit from one training hour...

Is there really a “menopause-specific” way to train, eat, and supplement — or is most of it marketing? In the finale of our 4-part menopause series, Drs. Jordan Feigenbaum and Austin Baraki go straight to the evidence on building muscle and bone before, during, and after the transition. We cover whether menopause blunts your response to lifting (the Isenmann 2023 head-to-head trial and the 2026 me...

Most women in 2026 are told menopause affects everything, the weight, the belly fat, the bones, the heart, the brain, and that the fix is hormones, supplements, and a proprietary protocol. The data tell a different story. Menopause does some of it, but not all of it. In this episode, Dr. Jordan Feigenbaum and Dr. Austin Baraki, with OB-GYN Dr. Loraine Baraki at the clinical handoffs, put real numb...

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...

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, D...

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 pas...

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 Kisspepti...

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 actu...

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...

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...

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 lau...

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...

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 medi...

In this free preview of the March 2026 Direct Line AMA. Drs. 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 tra...

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, ho...

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?. Dr. Jordan Feigenbaum and Dr. Austin Baraki break down the blind spot that sends thousands of healthy athletes down an expensive, potentially unnecessary diagnostic rabbit hole every year. Timestamps: 00:01:09   Intro...

In this special preview of the Barbell Medicine Plus Direct Line, Dr. Jordan Feigenbaum and Dr. Austin Baraki move past the fitness basics to tackle high-level technical nuances. 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...

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 scienc...

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...

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...

Can a simple one-second squeeze predict your risk of cardiovascular disease, cognitive decline, and all-cause mortality? Dr. Jordan Feigenbaum and Dr. Austin Baraki explore why grip strength has become the go-to metric for the longevity industry and why most people are interpreting the data incorrectly. Timestamps: [00:00]  Intro: The Longevity Industry’s Thermometer Error [01:42]  The Neuro-Axis:...

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...

In this episode, Dr. Jordan Feigenbaum and Dr. Austin Baraki dissect the federal government’s 2026 Food Pyramid Reset and its radical shift in nutrition policy. They explore the history of industry lobbying that shaped previous guidelines and evaluate whether the new emphasis on protein and animal fats aligns with current clinical evidence. Finally, the doctors provide the framework for the Barbel...

Fiber is the most underutilized tool in human nutrition. While the internet is currently buzzing about the new food pyramid and debating processed foods versus beef tallow, most people are missing the actual structural levers that dictate health and performance. Today, we are launching the Barbell Medicine Fiber Action Plan to bridge the gap between clinical science and your next trip to the groce...
