Show Notes
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, we talk with Dr. Kemi Doll, a double board-certified OB-GYN and gynecologic oncologist, about endometriosis, fibroids, uterine cancer, PMOS, and hormonal birth control. We examine how wellness influencers exploit real experiences of medical dismissal to promote fear, undermine trust in established treatments, and sell alternatives.
In this episode, Sarah Court and Laurel Beversdorf investigate the bone supplement company AlgaeCal and ask whether its marketing claims are supported by good evidence. They unpack the company's promotion of algae-derived calcium, its use of strontium supplements to claim increases in bone density, and why improvements on a DEXA scan don't necessarily mean stronger bones. Along the way, they explain how appeals to nature, authority, and fear are used to sell expensive supplements to women worried about osteoporosis.

In this episode, we look back at how our thinking about exercise has changed over the years, from our beginnings in yoga and physical therapy to strength training, bone density, power, fall prevention, and longevity. We talk about the ideas we stopped believing, the evidence that changed our minds, why "lift heavy shit" was an important corrective but ultimately an incomplete message, and how all of this has shaped the newest version of Lift for Longevity.
In this episode, we talk with bone health researcher Dr. Lora Giangregorio about what the evidence really says about resistance training, impact exercise, menopause, fracture prevention, balance, and falls. We also get into claims from OsteoStrong, why not all published research deserves equal weight, and why confident claims about the "best" way to build bone often outrun the evidence.
