Movement Logic: Strong Opinions, Loosely Held

In this in-between episode of the Movement Logic Podcast, Laurel discusses two major myths: the longevity significance of grip strength and the role of single leg exercises in improving balance. The discussion touches on the misinterpretations of grip strength's correlation with health and longevity, different types of grip and their training, and the genetic factors influencing grip strength. It also covers the efficacy of using gloves and straps. Additionally, the episode explores how single leg exercises contribute to overall strength and balance, challenging the notion that these exercises are essential for improving balance and athletic performance. 00:00 Introduction to Mythmas Season00:47 Debunking the Grip Strength Myth04:49 Understanding Different Types of Grip08:54 The Role of Genetics in Grip Strength17:25 Exploring Single Leg Exercises22:50 Benefits and Misconceptions of Unilateral Exercises31:09 Conclusion and Free Mini Course OfferGrab our Free Mini Course: Barbell 101Barbell GuideStronger By Science: The Evidence-Based Guide to Grip Strength Training & Forearm Muscle Development

In this in-between episode of the Movement Logic Podcast, Sarah discusses a new product for osteopenia called Osteoboost, a wearable medical device that uses gentle vibrations to improve bone density and strength, offering a non-invasive alternative to traditional treatments. Sarah delves into the research behind the device, its FDA clearance, and its effectiveness compared to medication and exercise. She emphasizes the importance of heavy lifting for bone health, and expresses concerns about people relying solely on passive treatments like Osteoboost instead of engaging in comprehensive exercise routines.00:00 Introduction and Episode Overview02:20 Introduction to Osteoboost03:00 How Osteoboost Works04:30 Research and Development Behind Osteoboost09:30 Clinical Trials and Results13:37 Comparing Osteoboost to Traditional Treatments17:21 Final Thoughts and RecommendationsOsteoboost websiteWellen websiteClick here to get on our mailing list for a FREE barbell mini course, access to discounts on our full Bone Density Program, and more!

In this solo episode of the Movement Logic Podcast, Laurel Beversdorf dives into the topic of exercise recovery. She differentiates between the physiological 'Big R' recovery and the 'little r' recovery, or aggressively marketed “recovery optimization” practices that the wellness industry loves to sell. Laurel discusses how sleep, nutrition, and strategic exercise stress management are critical to effective “big R’ recovery and clarifies why many marketed recovery methods may not be as effective as claimed. She emphasizes the importance of balancing exercise with adequate recovery to prevent injuries and achieve the positive adaptations and health outcomes we’re looking for when we exercise.Sign up for our free Bone Density Mini Course here!00:00 Introduction to exercise recovery01:23 Understanding recovery: the basics02:37 The rise of commercialized recovery “optimization practices” and why these are different from the recovery your body will do on its own if you let it.03:56 The essentials of recovery - time, resources, and strategy07:55 Misconceptions surrounding “recovery optimization” practices09:55 The importance of exercise12:27 Balancing exercise and recovery18:54 Practical tips for effective recovery28:26 Final thoughts and encouragementLinks:Good to Go: What the Athlete in All of Us Can Learn from the Strange Science of Recovery by Christie AschwandenDr Steph Mundt - managing bone stress injuries and relative energy deficiency in our athletes on the Movement Optimism podcastPost-exercise cold water immersion attenuates acute anabolic signalling and long-term adaptations in muscle to strength trainingResearch on cool downs:Pernigoni et al (2023) PMID: 37039750Afonso et al (2021) PMID: 34025459Mechelen et al (1993) PMID: 8238713CDC -  General Physical Activity GuidelinesLaurel's Instagram post about recovery

Bridgette, a 48-year-old yoga teacher from Canada, who is currently in perimenopause, and wanted to address the symptoms that she was experiencing as well as shore up some solid bones. Samm, a Pilates instructor and sports massage therapist from England, who got into Pilates to try and help her bad back.

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.

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.Sign up here 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!Analysis of the load on the knee joint and vertebral column with changes in squatting depth - PMID: 23821469Positive effects of moderate exercise on glycosaminoglycan content in knee cartilage - PMID: 16258919Thickening of the knee joint cartilage in elite weightlifters as a potential adaptation mechanism - PMID: 24648385Exercise for osteoarthritis of the knee: a Cochrane systematic review - PMID: 26405113Knee alignment does not predict incident osteoarthritis - PMID: 17393450Gluteal muscle weakness on joint kinematics - PMID: 37309814The effect of experimentally induced gluteal muscle weakness on joint kinematics - PMID: 37309814Impact of Three Strengthening Exercises on Dynamic Knee Valgus - PMID: 34068810Anteromedial versus posterolateral hip musculature strengthening with dose-controlled in women with patellofemoral pain - PMID: 33689989Kiss goodbye to the 'kissing knees' - PMID: 33906580Research on Crossfit injury risk - PMID: 24276294, PMID: 28253059, PMID: 32343082, PMID: 33322981Instagram post about Sharon Lokedi Low Prevalence of Hip and Knee Arthritis in Active Marathon Runners - PMID: 29342063
