129: Sarcopenia Redefined: Loss of Strength and Power Matter More Than Muscle Mass Video

Movement Logic: Strong Opinions, Loosely Held

Show Notes

A lot of people think sarcopenia means age-related loss of muscle mass. But this is not what it means!

This week on the Movement Logic podcast, Laurel and Sarah unpack sarcopenia: what it actually is, why the definition has changed over time, and why losing strength and power matters more than losing muscle mass. They walk through the evolution from a tissue-focused understanding of sarcopenia to a function-focused one. Learn how the nervous system plays a major role in aging-related decline, and how this explains a far more rapid loss of strength and an even more rapid loss of power. They discuss why resistance training is essential if you want to maintain independence, reduce fall risk, and preserve the ability to do the things you love as you age. They also discuss why yoga, Pilates, walking, and cardio alone are not enough to prevent sarcopenia, and why training strength and power is non-negotiable for long-term physical function.

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.

Sep 2, 2026

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.

Aug 19, 2026

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.
