In this episode, Sarah Court and Laurel Beversdorf continue their conversation with Dr. Stu Phillips, one of the world's leading protein researchers. They dig into the latest ACSM Position Stand on Resistance Training, unpacking what it actually says about strength, hypertrophy, power, progressive overload, and why many of the debates happening online are driven more by certainty than by evidence.

They also explore why protein has "jumped the shark," how marketing has outpaced the science, whether menopausal women really need dramatically more protein, and why consistency—not optimization—is still the most powerful exercise strategy. Throughout the conversation, Stu explains why scientific nuance often gets lost on social media and why changing your mind when new evidence emerges is a strength, not a weakness.

In this episode, Sarah and Laurel sit down with Dr. Stu Phillips, one of the world's most influential researchers in muscle physiology, protein metabolism, and resistance training. Together they discuss why Stu publicly challenged the idea that heavy lifting is required for bone density, what the evidence actually says about load and osteogenesis, and how newer research has changed the conversation around both muscle growth and bone health.

Stu explains why many long-held training beliefs—including the need for heavy weights for hypertrophy—have not held up under scrutiny, why good scientists must be willing to change their minds, and how concepts like effort and "progressive stimulus" may matter more than specific loading prescriptions.

The conversation also explores what researchers know (and still don't know) about bone adaptation, site-specific bone responses, impact training, mechanical loading, and the challenges of translating animal research into human recommendations. Finally, Stu shares his thoughts on protein obsession, exercise guidelines, weight loss stigma, and the importance of following the evidence wherever it leads.

What is balance, really? In this episode of the Movement Logic Podcast, Laurel and Sarah unpack why “balance” is much more than standing on one foot, not falling, or having a strong core.

Using the motor control concept of postural control, they explore balance as a dynamic, emergent process shaped by sensory input, motor responses, cognition, confidence, fear, environment, prior experience, and social context. They discuss center of mass, base of support, stability, perturbations, sensory reweighting, and why balance is deeply context specific.

You’ll learn why steady-state, reactive, and anticipatory balance are different biological problems, why yoga may train some balance skills better than others, why strength and power matter for fall recovery, and why no single “balance exercise” prepares you for every balance challenge life throws at you.
