Leslie Kaminoff on Yoga Anatomy, AI Book Fraud, and What Yoga Is

Matt interviews longtime yoga educator and Yoga Anatomy co-author Leslie Kaminoff. They cover Kaminoff’s at New York’s Sivananda, a brief period as a Swami, and his perspective shaped by over 20,000 hours of bodywork focused on breathing. They discuss AI-generated fraud flooding Amazon’s chair yoga rankings, ethical uses of AI as well as the need for critical thinking around “fantasy physiology,” fascia claims, and pain science (including asymptomatic MRI findings and biopsychosocial factors). They explore alignment as person-specific, long-term hip health, and Kaminoff defines yoga practice via Patanjali’s Kriya Yoga (tapas, svadhyaya, ishvara pranidhana) and the breath’s voluntary/involuntary nature.

What Is Prana? Bernie Clark on Breath, Yoga, Science, and the Evolving Story of “Life Energy”

The Galaxy Song with Eric Idle & Monty Python

Matthew Huy welcomes back yoga author Bernie Clark to discuss Clark’s book Prana: One Breath, Many Worlds and what prana and kundalini might mean in historical, yogic, and scientific contexts. Clark explains that “life energy” is a modern framing and traces prana’s roots in breath and ancient attempts to explain life before modern anatomy and experimentation, comparing Eastern and Western ideas and highlighting outdated beliefs like spontaneous generation and Greek theories of reproduction. They explore how science tests hypotheses, the risks of rejecting modern medicine for ancient claims, and how unexplained experiences can still be valid data. Clark proposes prana as “communication energy” or cellular signaling, discusses fascia research and meridian correlations as speculation, and shares personal stories about overdoing pranayama and pushing through pain in practice.

June 3rd Workshop: Alignment Doesn’t Prevent Injury — So What Should We Do Instead?

Use code POD20 for 20% off!

“Yoga butt” is often blamed on poor alignment in yoga poses. But is the science really that simple?

In this episode of the Enlightened Anatomy Podcast, Matthew Huy explores the research behind proximal hamstring tendinopathy (PHT), why alignment probably doesn’t predict injury as much as social media suggests, and why modern tendon science is more about load, recovery, and capacity than “perfect posture.”

Topics include:
• What PHT actually is
• Why “yoga butt” is a misleading term
• Tendon adaptation and the Cook & Purdam model
• Why pain ≠ tissue damage
• The limits of alignment-based explanations
• Load vs capacity in yoga practice
• Why fear-based cueing can backfire

In Defense of Vinyasa Flow: Modern Yoga History and the Science of Exercise Benefits

In episode 15 of the Enlightened Anatomy Podcast, host Matthew Huy defends strong vinyasa flow against claims that it’s “just gymnastics” or not “real yoga,” arguing that modern postural yoga itself is a recent synthesis rather than an unchanged ancient tradition. Drawing on Mark Singleton’s 2010 book Yoga Body, he explains how modern yoga developed through cross-pollination of Indian traditions and Western physical culture, with many iconic poses absent from classical texts like Patanjali’s Yoga Sutras. He then shifts to physiology, presenting strong vinyasa as intermittent bodyweight resistance work plus low-to-moderate aerobic stimulus that can improve cardiorespiratory fitness, mitochondrial function, metabolic flexibility, insulin sensitivity, and glucose regulation. He highlights benefits for muscle preservation against sarcopenia, bone and connective-tissue health via mechanical loading, and nervous system skills such as coordination, balance, motor control, breath regulation, attention, and interoceptive awareness, concluding that usefulness matters more than purity.

In this episode, Why Your Heart Loves Yoga with Dr. Sarah Samaan - Matthew Huy welcomes Dr. Sarah Samaan, a board-certified cardiologist with nearly 30 years of clinical experience, author of Best Practices for a Healthy Heart and co-author of Diet for Dummies, now a physician development coach blending medical expertise with mindfulness and yoga.

She shares how a 1997 horseback riding accident led her to yoga and how mindfulness practices improved her personal wellbeing and medical work, later informing coaching for physician burnout and stress resilience.

They discuss the limits of medical specialization, the value of team-based support, and the rise of patient distrust fueled by online misinformation. Dr. Samaan emphasizes that 75%+ of heart disease is preventable through exercise, not smoking, Mediterranean-style eating, healthy weight, sleep, and stress reduction, and highlights yoga’s physical, mindfulness, and community benefits. For yoga teachers, she advises deferring to medical clearance, offering general modifications, and letting students be experts in their own bodies.

In this episode of the Enlightened Anatomy Podcast, Matthew Huy explores the myth of the “pure yogi” — the unspoken belief that spiritual integrity and financial success are somehow incompatible. This episode steps slightly outside anatomy and physiology to look at how yoga shows up in our everyday lives as teachers, particularly in how we relate to money, pricing, and worth. The conversation is still research-informed, drawing on yoga history, sociology, and psychology to unpack where these ideas come from and why they persist in modern yoga culture.

Matt discusses how colonial reinterpretations of yoga, Western romanticisation of asceticism, and modern wellness culture have collectively stripped yoga of its social and economic context, leaving many teachers feeling guilt or shame around charging for their work. This episode also connects to a free workshop Matt is hosting on Thursday, February 12th, Why Making Money Feels Weird. You can learn more at matthewhuy.com or via the show notes. If you’re listening after that date, the workshop is available as an evergreen resource at matthewhuy.com.

Matt explores the popular claim that emotions and trauma are stored in the hips. Drawing on his background as a yoga teacher and anatomy educator with a master's in exercise science, he reviews scientific evidence to debunk this myth. The episode discusses how oversimplified views on trauma can create unnecessary fears and misconceptions, emphasizing the importance of precise language in yoga teaching. Additionally, Matt explains the real impacts of trauma on the brain and nervous system and considers why certain yoga poses might evoke emotional responses. The episode concludes with practical advice for yoga instructors on how to create a supportive environment without reinforcing unscientific beliefs.
