Movement Logic: Strong Opinions, Loosely Held

• Episode 92: Make Dr. Loren Fishman Make Sense

  In this episode of the Movement Logic podcast, Laurel and Sarah dissect a recent email they received from Dr. Loren Fishman, in which he expressed frustration over their critique of his study on yoga and bone density. In this episode, they address Fishman's email and take another look at his study, Twelve-Minute Daily Yoga Regimen Reverses Osteoporotic Bone Loss. Laurel and Sarah's conversation explores claims made in the email, as well as Fishman's study’s methodology and findings. They compare his claims against established evidence on bone adaptation and emphasize the importance of high-load and high-impact exercise for building bone. They also highlight the need for exercise recommendations to be grounded in solid, evidence-based research—especially for women looking to prevent or reverse osteoporosis and osteopenia.Get on the wait list for our Bone Density Course: Lift for LongevityFollow Movement Logic on Instagram00:00 Introduction00:47 Personal Updates & Course Insights14:25 Critique of Dr. Fishman's Yoga Study52:45 Critique of Yoga's Efficacy in Bone Building53:03 Mechanostat Theory and Bone Adaptation55:18 Challenges in Measuring Yoga's Impact on Bones01:06:17 Dynamic vs. Isometric Contractions in Exercise01:10:20 Unfalsifiable Claims and Scientific Inquiry01:15:16 Turkey Studies and Sustained vs. Intermittent Loading01:18:14 Dynamic Strength Training vs. Impact Training01:18:28 Cellular Accommodation and Running01:19:00 The Importance of Rate of Loading01:21:21 Critique of Yoga for Osteoporosis Claims01:26:24 Red Herrings and False Comparisons01:51:41 Concluding ThoughtsREFERENCESFishman’s StudyThe poses in Fishman’s studyTables of P values and more P values from Fishman’s studyEpisode 79: Make Yoga U Make SenseEpisodes on the Movement Logic podcast 5, 38, 51, 53, 84, and 88 that referenced Fishman’s paper.Episode 56 of the Yoga Research & Beyond podcast that looks at Fishman's paper.LIFTMOR trialLIFTMOR-M trialMedex OP Randomized Controlled TrialMeta-analysis on High-Load Resistance Training (HLRT)Systematic Review on Pilates and YogaBone "mass" and the "mechanostat": a proposal (Frost, 1987)Molecular pathways mediating mechanical signaling in boneEpisode 82: Weird Science1984 and 1985 Turkey Study

• Episode 91: LIFTMOR, Not Less: An Interview with Professor Belinda Beck

  In this episode of the Movement Logic Podcast, Sarah and Laurel are thrilled to interview esteemed exercise scientist Professor Belinda Beck, investigator in the groundbreaking LIFTMOR trial. They discuss the necessity of high-intensity resistance and impact training for improving bone density, comparing it to less effective exercises like Pilates, yoga, and walking. Professor Beck shares insights on her LIFTMOR, LIFTMOR-M, and MEDEX-OP studies, underlining the importance of mechanical loading for bone health. They explore the misleading promotion of devices like OsteoStrong or courses like Buff Bones that do not provide the necessary rate of loading or magnitude of load to impact bone density. The conversation elucidates the mechanisms of bone adaptation and defends high-intensity training as essential for combating osteoporosis.00:20 Bone Density Course Progress06:28 Guest Introduction08:25 Interview with Professor Belinda Beck16:59 Understanding Bone Health and Research23:46 Bone Adaptation and Remodeling36:15 Bone Remodeling and Exercise Breaks37:52 Exercise Types and Bone Response39:35 Strength Training and Client Engagement42:37 Effective Exercise for Osteoporosis44:00 Impact of Weight-Bearing Activities48:47 High-Intensity Training for Older Adults53:14 Impact Training and Bone Health01:02:12 Marketing vs. Science in Osteoporosis Treatment01:04:09 Comparing Exercise Programs for Bone HealthReferences:Get on the wait list for our Bone Density CourseOnero at the Bone ClinicBecome an Onero ProviderHigh-Intensity Resistance and Impact Training Improves Bone Mineral Density and Physical Function in Postmenopausal Women With Osteopenia and Osteoporosis: The LIFTMOR Randomized Controlled TrialA Comparison of Bone-Targeted Exercise Strategies to Reduce Fracture Risk in Middle-Aged and Older Men with Osteopenia and Osteoporosis: LIFTMOR-M Semi-Randomized Controlled TrialA Comparison of Bone-Targeted Exercise With and Without Antiresorptive Bone Medication to Reduce Indices of Fracture Risk in Postmenopausal Women With Low Bone Mass: The MEDEX-OP Randomized Controlled TrialREMS Echolight Bone ScanPaul Grilley Bone PhotographsMechanosensitivity of the rat skeleton decreases after a long period of loading, but is improved with time offEpisode 53: Your Bones Are BoredExercise to prevent falls in older adults: an updated systematic review and meta-analysisOptimum frequency of exercise for bone health: randomised controlled trial of a high-impact unilateral interventionOsteostrong: 3 Things You Should KnowTwelve-Minute Daily Yoga Regimen Reverses Osteoporotic Bone LossBuff Bones

• Episode 90: Capacities for Longevity Part 1: Strength

  We start off Season 6 with Part 1 of our 3 Part series on Longevity. What are the capacities we need to retain or develop in order to continue to live the lives we want to at the end of our lives? In Part 1, hosts Sarah Court and Laurel Beversdorf dive deep into the capacity of strength. We discuss the difference between strength endurance and maximal strength, and the myriad benefits of heavy strength training at any age. The episode includes discussions on common functional mobility tests for seniors, the neural adaptations resulting from heavy lifting, and practical guidelines for transitioning from endurance strength to heavy weights. Sarah and Laurel emphasize the long-term advantages of incorporating heavy lifting into regular exercise routines.00:00 Welcome to Season Six00:19 Couch Recording Fun01:14 Notes from the Bone Density Course04:59 Three-Part Series Introduction06:09 Strength and Longevity21:52 Strength Endurance Explained35:03 Maximal Dynamic Strength vs Isometric Strength42:44 Functional Tests for Seniors51:04 The Timed Up and Go Test54:29 Understanding Grip Strength and Its Importance01:11:42 The Five Times Sit to Stand Test01:13:38 Building Strength Endurance01:18:16 The Benefits of Heavy Strength Training01:33:53 Improving Bone Density Through Strength Training01:39:28 Enhancing Metabolic Function with Strength Training01:42:26 The Value of Strength for Longevity01:45:27 Conclusion and Final ThoughtsLinks:Timed Up and Go Test5x Sit to Stand TestSign up here to get on the Bone Density Course wait list and receive free content and the only available discount!

• Episode 89: Inbetweenie - Is Dead Butt Syndrome Real?

  In this episode of the Movement Logic Podcast, host Laurel Beversdorf explores the concept of 'dead butt syndrome' or 'gluteal amnesia', debunking both as a non-evidence-based myths perpetuated in fitness and health discussions. Laurel discusses the misleading information in a recent New York Times article titled Sitting All Day Can Cause Dead Butt Syndrome, and emphasizes the importance of evidence-based terms and ideas in understanding pain and body function. She outlines the dangers of accepting unsupported medical terms, advises on better exercise practices, and stresses the significance of regular, whole-body strength training for overall health. Listener feedback is also addressed, touching on the podcast's approach to myth-busting and health education.00:00 Introduction and Personal Check-In01:17 Understanding Dead Butt Syndrome03:03 Debunking the Myth: Evidence and Expert Opinions06:10 Critique of the New York Times Article09:12 Addressing Listener Feedback12:51 The Problem with Sensationalism in Media16:45 The Complexity of Pain and Misleading Diagnoses32:28 Exploring Gluteus Maximus Firing Patterns33:11 Factors Predicting Athletic Injuries33:48 Critiquing the New York Times Article34:18 Debunking Gluteal Amnesia Myths36:02 The Problem with Pathologizing Normal44:23 Understanding Muscle Cramping56:45 Effective Movement and Pain Prevention58:23 Upcoming Classes and CoursesFree offerings mentioned in this podcast:Take a free class with Laurel and get the replay - Escape the Gride: A Multi-Planar Banded FlowGet on the Waitlist for Bone Density Course and get the only discount for Spring 2025 cohortGet the free Bone Density Mini-Course: Barbell 101Resources mentioned in this podcast:Greg Lehman on "Trojan horsing" Conspirituality Podcast on Post-Truth AmericaSitting All Day Can Cause Dead Butt SyndromeHave the Butt Muscles of the World Gone Silent?Muscle Recruitment Patterns During the Prone Leg ExtensionTest showing more gm activity in presence of painPeople with low back pain do not have a delayed firing of GM
