The Discover Strength Podcast

What separates meaningful research from misleading results? In this episode, we sit down with Dr. James Steele to break down the most important—but often overlooked—aspect of exercise science: methodology. As part of our latest Project Discover study, we go beyond the headlines and dig into how research is actually conducted, why study design matters, and what it takes to produce results you can trust. Because in strength training, it’s not just what a study finds—it’s how it finds it. If you...

Should you combine strength training and cardio—or does one compromise the other? In this episode, we explore the concept of concurrent training and the long-debated “interference effect”—the idea that adding cardio to a strength program may blunt gains in muscle size and strength. For decades, researchers and practitioners have debated whether you can truly optimize both at the same time. We break down a brand-new study investigating strength training alone versus concurrent training, and wh...

Eccentric exercise might be the most important and most overlooked component of resistance training. In this episode, Luke Carlson breaks down the science behind eccentric contractions—the lowering phase of a lift—and explains why this often-neglected portion of an exercise may deliver the greatest return on your investment in the gym. You’ll learn: The fundamental differences between concentric, isometric, and eccentric muscle contractions Why eccentric training produces sup...

In this episode, we break down key insights from one of the largest gatherings in the fitness industry, where thousands of operators, leaders, and innovators came together to discuss the future of health and strength training. We explore what’s actually changing—AI, operations, and scaling businesses—and what isn’t: the enduring importance of human connection, high-quality coaching, and evidence-based training. If you’re interested in where the fitness industry is headed (and where Discover S...

In this week's episode of the Discover Strength Podcast, I had the pleasure of being joined by Dr. Stuart Phillips. Dr. Phillips is a senior lecturer at McMaster University in Hamilton, Canada. He is widely regarded as one of the preeminent researchers in the world on protein. While the topic of protein and how it affects our bodies can be very wide ranging, we tried to keep this episode down to the fundamentals. - What is protein? - Why do we need it? - How do we use it? - And finally can ...
