In this private preview, I’m sharing conversations with seven coaches who explain why they joined, what they were looking for, and how the program has changed the way they approach their clients and their businesses. Their backgrounds are different, but many of them reached the same point: macros, habits, and workouts were no longer enough to confidently support the more complex cases showing up i...

Before the podcast, the bestselling book, and the audience, I was making $7 an hour cleaning gym equipment. I worked low-paying jobs, made mistakes, volunteered for opportunities, and sometimes drove across town to speak to only a few people for barely enough money to cover the time and gas. In this clip, I talk about the unglamorous beginning of my career in health and fitness and why those early...

I’m 12 weeks into fatherhood, and the health operating system I’ve relied on for the last 20 years has been stress tested. Life is less predictable, sleep and schedules can change quickly, and the routines that worked in a different season may not be realistic right now. In this episode, I’m sharing what I’ve kept, what I’ve simplified, and what I’ve had to adjust while navigating a newborn, a dem...

Semaglutide, Tirzepatide, and Retatrutide are often grouped together as GLP-1 medications, but they are not simply three versions of the same drug. In this episode, I compare the biology, research, and real-world implications behind each compound, looking beyond the number on the scale to ask a more useful question: what type of weight is being lost? I break down the progression from single agonis...

If you are waiting until January to get serious about a health, fitness, personal development, or professional goal, you may already be giving away your biggest advantage. In this episode, I explain why September and October are some of the most underrated months to start making progress, especially when summer has disrupted your routines and the new year still feels far away. The goal is not to c...

What happens when coaches move beyond basic macros, calories, and training plans and learn how to work through the more complex health cases their clients bring them? In this episode, I’m sharing a mashup of FNMS student testimonials from coaches who came into the program with different challenges and different levels of experience. Some were struggling to solve client cases that no longer respond...

GLP-1 medications, reverse dieting, and ultra-processed foods are some of the most debated topics in health and fitness. The problem is that each conversation is often reduced to a simple yes or no: medications are either a solution or a mistake, reverse dieting is either essential or useless, and processed food is either harmless or addictive. In this replay conversation with Andrew, I work throu...

AI can score highly on medical exams, identify conditions in written cases, and still perform poorly when real people use it for their health. In this episode, I break down new research that tested what happens when members of the public use AI tools to interpret medical scenarios and decide where to seek care. The results point to a problem that has less to do with the model's knowledge and more...

Sophie Cunningham lit the internet on fire when she said we need to protect the safety of girls and the integrity of women's sports, and the conversation quickly turned into another political battleground even though the underlying question is really about biology, anatomy, and physiology. Inside today's episode, I break down what the research says about testosterone suppression, puberty, and the...

Roughly 1 in 4 American adults are taking 5 or more prescription medications at the same time, and that number climbs steeply for people over 40, for postpartum women, and for anyone managing more than one chronic condition. The most talked about murder trial of the year has put a public face on what polypharmacy looks like at its most extreme. I break down the polypharmacy conversation, walking t...

Inside today's episode, I break down the research on how anger affects the body from the inside out including the acute cardiovascular events, the chronic inflammatory picture, and the emerging cellular aging data. I walk through the acute mechanism starting in the amygdala and running through the sympathetic nervous system, the adrenaline and noradrenaline release, the peripheral vasoconstriction...

nside today's episode, I break down the emerging research on how high blood sugar affects the gut barrier and why hyperglycemia and leaky gut are more connected than most coaches and clinicians appreciate. I walk through the Danish observational study of 69,000 people with type 2 diabetes tracked over more than a decade, why cumulative A1C exposure predicted a 64% higher risk of hospitalizatio...

The PACE Framework for Keeping Clients Longer. Retention doesn't just keep clients. It turns them into your best marketing material through referrals and social proof, and it takes the pressure off the constant sales and marketing hamster wheel that so many coaches end up trapped on. Inside today's episode, I break down the retention math most coaches never actually run, the three framing...

Your immune system is built to hunt invaders, but every so often it turns its weaponry on your own tissues. Over the last 50 years, autoimmune disease has gone from an uncommon condition to something almost everyone knows at least one person living with, and the two variables that move symptoms more than anything are almost never discussed in a 10-minute doctor's appointment. Inside today's episod...

Inside today's featured replay interview, I walk through how to assess metabolic health from both the subjective side of energy, sleep, and appetite regulation and the quantitative side of lab work, and why coaches are best thought of as adaptation managers rather than diet prescribers. I cover the five pillars I use for managing metabolism including managing appetite, maximizing adherence, ma...

The FDA advisory committee voted July 23rd and 24th and social media has been running wild with the news, but most of what's circulating about BPC 157 and the other peptides that were on the agenda is either half-right or completely wrong. Inside today's episode, I break down what happened at the FDA's Widow campus in Silver Spring, what the 8 to 6 to 1 vote on BPC 157 means, and how to think abou...

80% of Americans are metabolically unhealthy, which means the obesity conversation isn't about weight for a lot of people... It's about internal health markers that indicate a declining state of metabolic function regardless of what someone weighs. Inside today's episode, I get into the harder version of the obesity conversation including whether it should be classified as a chronic me...

People spend over $36 billion a year on vitamins, and most people probably couldn't tell you what those nutrients are supposed to accomplish. The multivitamin is the most popular supplement on Earth, but it's also one of the most mocked and misunderstood, with one camp calling it a scam while another swears a special formulation changed their energy and their life. Both takes miss the poin...

Inside today's featured replay interview, I sit down at the Silverback Summit for a full conversation on what it takes to start and grow a health coaching business that lasts. I get into the five categories that stack together to build coach credibility including leading by example, education and mentorship, content creation, networking, and the social proof that comes from actually helping people...

Hair loss is one of the most common health concerns out there, and it's one of the most mishandled. It directly impacts someone's confidence and the way they feel when they look in the mirror, and the standard response from coaches and providers tends to be the same advice across the board no matter what the actual mechanism is. Inside today's episode, I break down the three completely...

Most of the conversation around nutrition in the fitness industry is really diet culture in disguise. There's a cookie-cutter template at the end of every book, a subscription waiting on the other side of every plan, and almost no one is actually teaching people how to think critically about the choices they make for their bodies. Inside today's featured replay interview on the Strong New York pod...

Most adults dealing with acne have been handed the same three pieces of advice for the last 20 years. Wash your face more, cut out greasy food, try this cream, and if none of that works, get sent to a dermatologist for topical retinoids, oral antibiotics, or Accutane. None of that touches the actual drivers of adult acne. Inside today's episode, I break down what the research actually says abo...

Inside today's featured replay interview, I get into the broader conversation on metabolic health and why I treat calories and hormones as inseparable rather than opposing camps, what a comprehensive lab panel should actually include, and how to think about the testosterone conversation without overreacting. I cover the role of leptin, ghrelin, and GLP-1 in appetite regulation, the homeostatic...

Most people are paying for grocery labels that aren't doing anything for them, and the FDA doesn't regulate half the words you're paying extra for at checkout. Inside today's episode, I walk through the food quality labels you see every week in the grocery store, which ones are tightly defined, which ones are basically marketing, and where the premium actually earns its keep depending on the categ...

The TRT advice circulating online right now is mostly targeted at one demographic, and it's being applied by people at completely different stages of life, with different goals, different health risks, and very different time horizons on medication. Inside today's featured replay interview, I get into testosterone replacement therapy, the test club industry that's popping up everywhere...
