Mark Bell's Power Project

Steven Scott, founder of CarboGenetics, researches carbon dioxide physiology and develops experimental CO2 products. He explores how CO2 may influence oxygen delivery, blood flow, nasal breathing, athletic performance, recovery, brain health, mitochondria, neuropathy, and longevity. The conversation also examines omega-3 oxidation, naked mole rats, breath holds, the Bohr effect, and transdermal CO2 therapy.

Dr. Michael Twyman, a preventive cardiologist and founder of Apollo Cardiology, examines Mark Bell’s heart scans and hidden cardiovascular risk. They explore soft versus calcified plaque, CAC scores versus CT angiograms, ApoB and advanced lipid testing, saturated fat, genetics, anabolic steroids, exercise, sleep, stress, supplements, medications, and the essential markers for long-term heart health.

Mark Bell and Nsima Inyang explore why progress depends on skill, technique, and composure, not just harder work. They discuss running mechanics, sprint drills, athletic versatility, meditation and presence, and testing advice for yourself. Competition, jiu-jitsu losses, acting, learning new skills later in life, and the patience required to improve all take center stage.

Cal Dietz, an Olympic and world champion strength coach and creator of Triphasic Training, explores the science of explosive athletic performance. He discusses hockey conditioning, injury prevention, foot and big-toe mechanics, plyometrics, individualized technique, recovery tracking, carbohydrates, and single-leg strength work. The conversation also covers youth athletic development, coordination drills, elite movement archetypes, and staying powerful with age.

Ryan Rosner, PhD, is a geneticist researching performance, longevity, mitochondria, and gene therapies. He explores what elite athletes’ DNA can reveal, “superhuman” mutations, embryo editing, genetic protection from disease, cognition, bone density, and Alzheimer’s risk. The conversation also tackles mitochondrial metabolism, supplements, metabolic flexibility, privacy, and whether humans are nearing the ability to deliberately redesign biology.

Steve Gentili, a strength athlete, powerlifter, and Indianapolis gym owner, recounts the shocking kidney failure that ended his pursuit of a 2,000-pound total. He shares five years on dialysis, a life-changing kidney donation from his sister, and the struggle to rebuild his identity beyond lifting. The conversation explores family, faith, bloodwork, responsible hormone care, near-death experiences, and keeping a business alive through illness.

Jonathan Jarecki, a health and science communicator studying biology and neuroscience, explores how light shapes human health. He compares sunlight with commercial red-light devices and examines mitochondrial function, circadian rhythms, vision, vitamin D, sunscreen, and skin cancer. They also tackle the risks of modern indoor lighting and practical ways to improve daily light exposure.

Shaun Vasquez, a professional bodybuilder, Army veteran, father, and founder of Pride Foods, shares his journey from childhood trauma to strength. He discusses surviving abuse and loss, joining the Army, rising in bodybuilding, and building Rice and Grinds. The conversation explores psychedelics, fatherhood, breaking generational cycles, entrepreneurship, and smarter training for chest development.

Dave Knapp, independent creator behind On The Pen who researches GLP-1s and metabolic health. He recounts his diabetes diagnosis and path to studying peptide therapies. Conversations cover how GLP-1s began, access routes and dosing, mental tradeoffs like anhedonia, preserving muscle during rapid loss, and next-generation combination drugs.

Ben Askren, former elite wrestler and pro fighter who survived a life-threatening infection and double lung transplant. He recounts waking with no memory, rebuilding from 195 to 138 pounds, breath training and inspiratory devices, choosing the comeback match, and how surviving shifted his faith and priorities. Short, intense stories of recovery, rehabilitation, and returning to the mat.
