S 942: Overcoming Adversity and Building a Coaching Career That Lasts
Episode 942
Tuesday, October 20, 2026 • Duration 01:01:18
In this conversation, my close friend Grant hosts an honest interview about navigating adversity, building a coaching career, and continuing to show up when life and business do not go according to plan.
We talk about the experiences that shaped my approach to leadership, responsibility, and consistency, including the difficult seasons, uncertainty, and professional setbacks that are usually left out of the success story. I share how I’ve learned to keep moving through competing demands, family responsibilities, business challenges, and the moments when it would be easier to question whether the path is still worth pursuing.
Join me for an exclusive Metabolism School Live Event interview.
S 941: 7 Coaches Share Their Experience With the FNMS Program: What it’s really like inside Metabolism School
Episode 941
Tuesday, October 13, 2026 • Duration 19:58
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 in their coaching practices.
If you’re considering further education, feeling limited by the tools you currently have, or trying to decide whether FNMS is the right next step for you, these conversations will help you understand what the program looks like from the inside.
S 940: Industry Advice: very Coach Needs to Hear to Build a Career in Health & Fitness
Episode 940
Wednesday, October 7, 2026 • Duration 08:54
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 experiences mattered. Building a reputation, developing a point of view, and creating opportunities rarely happens overnight. It usually comes through years of work that feels small, uncertain, or invisible to everyone else.
Topics discussed:
- Starting a career
- The early jobs that shaped my approach to health and fitness
- Building credibility
- Why opportunities often require showing up without recognition
- The adversity behind careers that look successful from the outside
S 938: My Health Operating System When Life Gets Harder: 12 Weeks Into Fatherhood
Episode 938
Tuesday, September 22, 2026 • Duration 23:43
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 demanding work schedule, training, nutrition, and family responsibilities.
Topics discussed:
- What changed when I became a father
- The health habits that survived a major life transition
S 937: Battle of the GLP-1s: Semaglutide vs Tirzepatide vs Retatrutide
Episode 937
Tuesday, September 15, 2026 • Duration 30:02
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 agonist to dual agonist to triple agonist, including how GLP-1, GIP, and glucagon signaling may influence appetite, glucose regulation, energy expenditure, and fat loss. I also examine what the available body composition research shows about lean mass, visceral fat, skeletal muscle, and the risk of becoming lighter without becoming healthier or stronger.
Topics discussed:
- What actually separates the major GLP-1 medications
S 936: Building Fall Momentum: Why September and October Are the Best Months to Start New Goals
Episode 936
Friday, September 11, 2026 • Duration 19:01
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 create another short-lived resolution. It is to use the fall to build 90 to 120 days of momentum, test your schedule, establish new habits, and learn what actually works before January arrives. By the time everyone else is making a list of goals, you can already have weeks of workouts, better routines, new skills, or meaningful progress behind you.
Topics discussed:
- Better starting points than January
- The overlooked opportunity
- How to build 90 to 120 days of momentum
- Why predictable time matters
- Using the fall to test and adjust your plan
- Turning January into a checkpoint instead of a restart
S 935: Inside FNMS: The Coaching Upgrade that creates better client outcomes and stronger businesses
Episode 935
Tuesday, September 8, 2026 • Duration 13:54
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 responded to more dieting or more training. Others wanted a stronger understanding of functional health, more confidence working with labs, or a way to apply what they were learning instead of simply completing another course.
You’ll hear how coaches used the FNMS education, mentorship, casework, and ongoing support to improve client retention, work through more complicated cases, grow their businesses, and become more confident collaborating with other health professionals. Several students also describe the personal impact of learning to look more deeply at their own health and the factors affecting their clients.
S 934: What Health and Fitness Gets Wrong About GLP-1s, Reverse Dieting, and Processed Foods
Episode 934
Thursday, September 3, 2026 • Duration 17:47
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 through the gray areas behind these topics.
Topics discussed:
- The gray areas behind today's most debated weight loss tools
- What GLP-1 medications change about hunger and metabolism
- When reverse dieting may help, and when it may backfire
- A more useful way to think about processed foods
- The health factors that matter beyond calories alone
- How to make better decisions when the answer is not black and white
S 933: The AI Medical Diagnosis Problem: Why Accuracy Falls Apart in Real Conversations
Monday, August 31, 2026 • Duration 14:35
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 to do with the human interaction around it.
S 932: Reacting to Sophie Cunningham and Trans-Athletes in Women’s Sports: Hormone Science, Skeletal Structure, and Aerobic Capacity
Episode 932
Tuesday, August 25, 2026 • Duration 24:24
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 physiological differences between men and women that don't disappear just because testosterone levels come down.
Topics discussed:
- A Brief History of Trans Athletes in Sport
- Pre-Puberty Differences Between Boys and Girls
- What Male Puberty Does That Can't Be Reversed
- What Testosterone Suppression Does and Doesn't Change
- Bone Density, Muscle Mass, and Neural Capacity
- Spironolactone, Oral Estradiol, and Half-Life Windows
