Boundless Life

In this episode, you'll get a practical, plain-language tour of breathwork with Nick Sweeney, a breathwork coach who rebuilt his body with breath after a college bike accident left him unable to walk. You'll learn his Vortex Breath and the Fibonacci counting behind it, why slow breathing is really cardiovascular training that may predict how long you live, how to pair breath with fascia and mobility work, his routines for better sleep and for combining sauna, breath, and cold safely, where he lands on the cold plunge debate, why the air you breathe matters as much as how you breathe, and his "Billions Will Breathe" mission to get a million (and eventually a billion) people breathing in sync.
Nick is the founder of Coherence, a breathwork app that trains your nervous system to improve deep and REM sleep, HRV, and stress resilience. After doctors told him his skiing career was over, he went from unable to walk to competing at U.S. Nationals within a year using breathwork, cold, and nervous system work, and today he leads a global movement to have people breathe together as one.

In this solosode, you'll get the latest research on the questions I hear most: whether the peptide BPC 157 can cause cancer, the body fat percentages people rate most attractive for men and women (and how low is too low), how a "dad bod" before conception can affect your future kids' health, how "myo-reps" deliver the same strength and size gains in a fraction of your gym time, and whether creatine is bad for your kidneys. You'll hear why BPC 157's blood-vessel growth is not the same as the way cancer feeds a tumor and why healthy tissue has nothing to fear from it, how excess body fat quietly lowers testosterone, and why the most attractive body fat ranges line up almost perfectly with the ranges that support healthy testosterone, fertility, and a long life. You'll also walk away with the body fat targets actually worth aiming for, a simple way to shorten your time in the gym, and the creatine myths you can finally stop worrying about.

In this episode, recorded at Lightsey Family Ranch in Venus, Florida, I'm joined by my sons River and Terran and repeat guest Adam Wenguer, founder of Element Health, for the first stop in a father-and-sons adventure project inspired by former Boundless guest Sahil Bloom's The 5 Types of Wealth.
You'll hear the ethics and deeper meaning of hunting, why harvesting your own meat changes your relationship with food, and how to cook wild game so it actually tastes great. We also get into spearfishing and free diving, teaching kids breath work and comfort with heat and cold from a young age, and a grounded, plain-language look at cannabis and the endocannabinoid system, including how CBD, CBG, and CBN each work.
Adam is a University of Florida graduate in applied physiology and kinesiology who spent more than a decade as a strength, conditioning, and health coach at a five-star wellness resort before founding Element Health in 2017. He is a Brazilian jiu-jitsu black belt, a meditation practitioner, and a passionate advocate for ethical, conscious hunting, and he lives on a farm in Florida with his family.

In this episode with Luke Chapman and Owen Buchanan, founders of Western Sol, you'll hear the story behind the custom sauna I recently had built in my backyard in Idaho, and the story behind the company itself, which started when a mold exposure in Hawaii sent Luke into daily sauna use. You'll gain insights into the actual science of heat shock proteins and dynorphins (the opioid peptides your body releases under heat stress), why most sauna wood is loaded with VOCs, and how thermally pressed aspen and spruce sourced from Estonia solves that problem entirely. We'll also touch on how Western Sol engineers oxygen-rich air recirculation, Himalayan salt therapy, and even full electrical grounding directly into the sauna floor, and you'll get a full walkthrough of what it costs to get a custom or prefabricated sauna built.
Luke Chapman and Owen Buchanan are the founders of Western Sol, a custom and prefabricated sauna company based in Idaho. Both grew up around custom home construction in their family businesses before turning their focus toward building non-toxic, low-VOC saunas designed to support healing of the mind, body, and soul. They travel throughout Europe to source materials and study traditional sauna culture at its origin.

In this episode with Tom Moss, founder and CEO of Vital Signals, you'll hear how a near-fatal hypertensive crisis during a family vacation became the founding moment for a device that may finally solve the problem of getting accurate blood pressure readings in real life without a cuff. Tom explains why blood pressure is the single most important indicator of long-term cardiovascular health and yet one of the least accurately measured, what the cuff gets wrong, and how Vital Signals achieved the scientific breakthrough that other companies failed to crack: accurate, calibration-free blood pressure monitoring from a ring. You'll also hear about the interplay between sleep, stress, hormones, sauna, cold, and blood pressure, what the Signal Ring's data is already revealing about human arterial health, and where this technology could go over the next decade.
Tom Moss is the founder and CEO of Vital Signals, building at the intersection of heart health, technology, and everyday behavior. After his experience with undiagnosed hypertension, he became focused on why some of the most critical health signals remain so difficult and often stressful to understand.
Pre-order your Signal Ring from LIFE Market and measure your blood pressure without the cuff. Ships October 2026.
