In this episode of the Movement Logic Podcast, Laurel and Sarah talk with registered dietitian and longtime myth buster Abby Langer, RD, about what it actually means to eat in a healthy, sustainable way. Abby brings clarity to some of the most confusing and overhyped nutrition messages online, explaining the meaningful difference between dietitians and nutritionists, why food guidelines get so much misplaced blame, and why simple habits like eating more fiber, plants, and whole foods still matter far more than clean eating, hormone-balancing diets, or supplement-driven solutions. She breaks down ultra processed foods, weight gain misconceptions, what causes overeating, and why carbs, fruit, sugar, and seed oils have all become targets of unnecessary fear.

The conversation also explores protein needs, plant versus animal protein, the role of fiber in digestion and satiety, what gut health is and isn’t, and why probiotic claims are often overstated. Abby shares how her decades of experience in hospitals, primary care, and private practice have shaped her evidence-based approach, and she offers grounded advice on how to build a sane, less anxious relationship with food in a culture that thrives on extremes.

In this episode of the Movement Logic Podcast, Sarah discusses two primary methods for measuring bone density: DEXA (Dual-Energy X-ray Absorptiometry) and REMS (Radiofrequency Echographic Multi-Spectrometry). The episode explains what each method measures, their technologies, reliability, and practical applications. It compares their availability, cost, accuracy, and limitations. DEXA is recognized as the clinical gold standard but has some limitations, while REMS, although newer, shows promise with advantages in certain clinical situations.

In this episode of the Movement Logic Podcast, Laurel Beversdorf talks with strength coach James Lederach, MS, CSCS, about the deeper side of coaching and how helping someone get stronger often means helping them grow as a person. Together, they explore the benefits of strength development for adults and kids, training that supports rather than interferes with sport, the downsides of early sport specialization in youth, and the broader life lessons that strength training offers beyond physical health and performance.

James and Laurel reflect on how training develops resilience, self-reliance, and emotional steadiness for both kids and adults. They discuss how good coaching balances structure with empathy, how strength training teaches self-trust, and why the most meaningful outcomes of training have less to do with performance and more to do with who we become through the process.

In this episode of the Movement Logic Podcast, Laurel Beversdorf and Dr. Sarah Court examine the enduring myths and misinformation around the aesthetic goal of “getting abs.” They analyze the anatomy and function of the abdominal muscles, the cultural evolution of ab training versus core strength and stability training, and the role mechanical tension, muscle length, and training volume play in hypertrophy (muscle growth). Additionally, they discuss how pursuing the aesthetic goal of "getting abs" is different from performance goals related to abdominal strength.

The hosts unpack popular misconceptions, such as “abs are made in the kitchen,” or that body composition changes work differently for women than men, or that core stability means never moving your spine. They contrast these myths with what current research on energy balance and hypertrophy training show. They also trace how Pilates, physical therapy, and social media helped shape the modern core strength and stability narrative—one that, in some circles, shifted from building strength through movement to “protecting” the lumbar spine by avoiding it.

Additionally, this episode aims to clarify all of the factors that influence the appearance of the abdominal region, and how gendered, moralized, and shame-based messaging about the midsection continues to distort public understanding of exercise and body image.

Welcome to Episode 112 of the Movement Logic Podcast! In this special episode, Laurel and Sarah talk to four women who recently completed Lift for Longevity about their experiences. Whether it’s overcoming fear of injury, finally finding a program that sticks, breaking free from perfectionism, or realizing barbells belong in their hands, each woman brings a unique and inspiring story.

In this episode, you’ll hear from:

Karen Klubertanz, an interior designer and yoga therapist who came to us after chronic back pain and years of yoga and kettlebells. Her story is about overcoming fear, learning to train with RPE, and discovering she could get stronger safely and sustainably.

Anna Grojec, a freelance writer and editor in New Jersey who found us through the podcast and has now completed the course twice, entirely asynchronously without ever taking a live class. Her story is about making strength training stick for the first time in her life through structure and community support.

Terry Littlefield, a longtime yoga teacher and old friend of Sarah’s who came in skeptical, took our free class, and realized she had to join. Her story is about shifting from perfectionism to consistency and finding confidence under the barbell.

Janai Leeb, a personal trainer in northern Los Angeles County who first got the impression in her PT cert that barbells weren’t for her. She joined to build her own barbell skills and now teaches them to her clients. Her story is about finding her lane with the barbell and showing others that anyone can lift, at any age.

If you’ve ever wondered if you’re too old, too inexperienced, or too "not a gym person" to lift barbells and get stronger, these conversations will change your mind.

In this episode, Laurel and Sarah take a look at one of the most influential and controversial voices in women’s health: Dr. Stacy Sims. Known for the phrase “women are not small men,” Sims has built her brand on the idea that women need entirely different training and nutrition strategies than men.

Laurel and Sarah trace Sims’ rise to prominence, the research she leans on, and the rhetorical playbook she uses on major platforms like the Mel Robbins Podcast, and the Huberman Lab podcast. They examine how Sims’ is able to persuade listeners of her ideas, even though her catchy slogans and bold claims outpace the evidence.

Rather than just fact-checking Sims’ most dubious claims on cycle syncing, fasted training, cardio, and how women should train, this episode instead focuses on how Sims’ messages are delivered. You’ll listen for how Sims’ and the hosts of these podcasts frequently employ persuasive tactics like appeals to authority, fearmongering, absolutist framing, pseudo-feminist virtue signaling, and what Laurel and Sarah call “mechanism theater” can make the weak evidence and shaky reasoning behind the claims sound stronger than it is. These strategies aren’t unique to Sims; you’ll start noticing these persuasive tactics everywhere, especially in menopause marketing and wellness content online.

In this episode, Laurel and Sarah sit down with  muscle physiology researcher and science communicator Lauren Colenso-Semple to take a hard look at some of the most popular and problematic claims circulating in women’s health and fitness. Together, they unpack the slogan “women are not small men,” and the idea that women need completely different training and nutrition approaches than men. Lauren explains where the evidence actually stands on topics like muscle loss at 30, lifting to failure, cardio recommendations for women, bone density changes at menopause, training fasted versus fed, cycle syncing, cortisol “hacks,” and more.

This conversation is a deep dive into separating women's physiology from marketing ploys. Learn why overcomplicating women’s training does more harm than good. You'll gain clear, evidence-based guidance for women in perimenopause, post-menopause, and beyond.
