    Episode 82: Weird Science: When It Doesn't All Add Up

    Welcome to Season 5, Episode 82 of the Movement Logic podcast! In this episode, Laurel and Sarah navigate the worlds of science, pseudoscience, and outdated science. We'll be looking at claims from a range of topics, including crystals, Reiki, and Ayurveda, to personality tests, fad diets, yoga, Pilates, physical therapy and CAM treatments. Our discussion is organized around the "non-negotiable ingredients" of a science-based claim to separate pseudoscience from outdated ideas and solidly science-based claims.

    Episode 80: Posture Panic Pt. 3 with Author Dr. Beth Linker, PhD

    Welcome to Episode 80 of the Movement Logic podcast! In this episode, Laurel and Sarah are joined by Dr. Beth Linker, PhD.

    Episode 79: Make Yoga U Make Sense

    Welcome to episode 79 of the Movement Logic Podcast! Laurel and Sarah explore whether yoga strengthens bones, examining Yoga U's claims and Dr. Loren Fishman's controversial study. We'll uncover how Yoga U often exaggerates or cherry-picks evidence while overlooking effective bone-building exercises like heavy resistance and impact training. In this episode, you will learn: * How research can be misrepresented to support biases. * The difference between bone resorption and bone-building. * Why yoga isn't effective for bone strengthening due to lack of adequate loading and progressive overload. * The limitations of yoga's balance improvements for real-world activities. * The importance of critically evaluating research claims about yoga and bone health.

    Episode 78: Behemoth Knee Myths

    Welcome to Episode 78 of the Movement Logic podcast! In this episode, Laurel and Sarah discuss what current science, versus outdated advice and conventional wisdom, have to say about the knees—namely whether "bone on bone" is a thing, and if deep squats, knee valgus aka "knee cave", or high impact are inherently bad for your knees. Learn what research has to say about some of the most common fragilizing beliefs people hear about their knees, and why these scary tales are just plain wrong. In this episode you will learn that: * The knee is strong and adaptable, capable of handling various loads with training. * The knee has a wide range of safe positions, especially with progressive exposure. * Knee pain doesn't always mean injury, and injuries can heal with proper care. * The knee isn't a simple hinge; it allows rotational and lateral movement. * The kneecap doesn't always need to face forward in standing. * Knees can lock or hyperextend without causing harm, depending on the person. * The knee can safely move past the ankle and toes during squats or lunges. * Running and landing don't require the knee to track perfectly forward. * Knee valgus is not inherently dangerous. * Deep squats, high-intensity exercise, and running do not cause arthritis or "wear and tear"; they strengthen the knee. * Strength training and running thicken knee cartilage compared to inactivity.

    Episode 77: Are You Getting DEXA Scammed?

    Welcome to Season 5 and Episode 77 of the Movement Logic podcast! In this episode, Laurel and Sarah dive into the history of how DEXA scans came to be so ubiquitous, what are the risks around osteoporosis medication, and whether osteoporosis and osteopenia were intended to be diagnoses in the first place. You will learn: * How was the DEXA score for osteoporosis first decided on * Was osteopenia supposed to be a diagnosis for treatment * What role did Merck play in getting more women to take their new drug Fosamax * What are the risk factors for the side effects of bisphosphonate drugs * What is the difference between a population risk vs an individual risk * Why it's not recommended to get a DEXA scan before you are 65 years old * The role of iatrogenesis in the medication choices and use for women with osteoporosis Sign up here [https://mailchi.mp/bae2c94fafb7/livestrengthclass] for our FREE Live Strength Class (and sample our Bone Density Course) on September 19th at 8:30am PT/11:30am ET with free replay!

    Episode 76: Posture Panic Part 2

    Welcome to Season 5 and Episode 76 of the Movement Logic podcast! In this second episode in our Posture Panic series, Laurel and Sarah take a deep dive into the currently available research around posture to debunk some of the long held beliefs around posture, pain prevention, muscle activation, and more. You will learn: * Does good posture keep you pain free? * Is Text Neck or Tech Neck really a thing we need to worry about? * Do we need to spend so much time finding a "neutral spine"? * Do you need to keep your shoulders "back and down" at all times? * Does a flexed spine automatically lead to a disc herniation? * What the actual predictors of pain and injury are (spoiler: it's not your posture) * Why we hate @postureguymike's fearmongering pseudoscience approach to "strength" for seniors And more!
