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.
