Enlightened Anatomy with Matthew Huy

Do yoga twists really detox your body? Should you keep your hips square, lengthen your spine before rotating or avoid twisting your lower back?

In this solo episode, recorded during his yoga retreat in Portugal, Matt explores the anatomy of spinal rotation, common misconceptions about twisting poses and practical ways to bring more variety into your yoga teaching.

In this episode:

• Why your thoracic spine rotates more than your lumbar spine
• How your neck, hips and shoulders contribute to twisting poses
• Whether your hips really need to stay square
• Why lifting your shoulder in a reclining twist isn't necessarily wrong
• What actually happens when you cue students to lengthen their spine
• Inhaling, exhaling and exploring different spinal positions
• Active versus passive-assisted twists
• Why twists don't detox your liver
• What we know—and don't know—about twists and digestion
• How to teach twists without rigid alignment rules

September's focus inside the Enlightened Yoga Collective is twists, including a practical class exploring different ways to rotate.

Episode 20: Daniel C. Simpson on What We Get Wrong About Yoga

What is yoga really—and how much of what we practise today actually comes from ancient tradition?

In this episode, Matt Huy talks with Daniel C. Simpson, author of The Truth of Yoga and teacher at the Oxford Centre for Hindu Studies, about the history and philosophy of yoga, how yoga has evolved, and why there may never have been one single “true” yoga.

Simpson challenges some common assumptions about yoga’s past while exploring how we can engage with ancient teachings without treating them as unquestionable truths.

In this episode, we explore:

• Why there is no single “true” version of yoga
• The origins of chakras—and why the modern rainbow chakra system isn’t ancient
• Why chakras shouldn’t simply be mapped onto nerves or endocrine glands
• How yoga evolved from meditation and breath awareness into modern postural practice
• Tapas, discomfort and learning to be okay when things aren’t okay
• Desire, suffering and what yoga teaches us about contentment
• Why Patanjali’s Yoga Sutras may be very different from how they’re presented on teacher trainings
• The supernatural siddhis described in the later Yoga Sutras
• How the Bhagavad Gita offers a very different vision of yoga
• Dharma, right action and acting without attachment to the outcome
• Why modern postural yoga isn’t “wrong” simply because it’s modern
• Krishnamacharya, Kuvalayananda and the development of modern asana
• Cultural appropriation, colonialism and how yoga traditions have always borrowed and evolved
• How yoga teachers can bring more philosophy into classes without turning them into lectures
• Why critical thinking belongs at the heart of yoga

Balance is the monthly inspiration at the Enlightened Yoga Collective, the go-to learning community for yoga teachers: https://enlightenedyogacollective.com/.

Episode 19 of the Enlightened Anatomy Podcast examines what balance is, how it changes with age, whether yoga improves it, and whether better balance reduces falls. The host discusses a 2025 randomized controlled trial of 700 people comparing online Iyengar yoga to seated meditation that found a 33% higher fall rate in the yoga group, noting this doesn’t prove yoga causes falls and must be weighed against broader evidence.
 
Balance is defined as keeping the center of mass over the base of support and is influenced by sensory systems (vision, vestibular, proprioception, skin), motor output, cognition, and environment, with multiple types (static, dynamic, proactive, reactive, functional). Reviews show balance training improves balance, while a 2019 Cochrane review found exercise reduces falls about 23% and balance/functional exercise about 24%; yoga shows small balance and medium mobility improvements but unclear fall reduction.
 
The episode suggests adding dynamic transitions, reaching, stepping, turning, progressive challenges, and embracing “the wobble.”

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.
