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’ve ever wondered why studies seem to contradict each other, or how to separate high-quality evidence from noise, this episode will change the way you think about fitness research—and how you apply it to your workouts.

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 what the latest evidence tells us about hypertrophy, performance, and overall health outcomes. Does cardio actually interfere with your results, or is the concern overstated?

As always, we cut through the noise and focus on what matters most: how to apply the science in a way that helps you train more effectively—and get better results.

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 superior strength and hypertrophy adaptations
• How eccentric loading impacts muscle physiology and long-term health outcomes
• Practical ways to incorporate eccentric-focused training into your workouts

If your goal is to train smarter, not just harder, this episode will challenge how you think about every repetition you perform.

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 Strength fits into that future), this conversation highlights the trends that matter—and the noise that doesn’t.

n this episode of the Discover Strength Podcast, CEO and exercise physiologist Luke Carlson breaks down new research on resistance training and fat loss. He reviews a recent study published in Frontiers in Endocrinology and connects it to over a decade of evidence on how strength training influences body composition.

Luke explains why the goal of weight loss should be fat loss—not just a lower number on the scale—and how resistance training helps preserve or increase lean muscle while maximizing fat reduction. He also explores the critical role of abdominal fat in cardiometabolic risk and what the latest findings reveal about reducing central obesity.

If you want to understand the science behind “high-quality weight loss” and why lifting weights is essential for long-term health and weight maintenance, this episode delivers the key takeaways.

In this episode of the Discover Strength Podcast, Luke Carlson sits down with Rick Rignell to reflect on the life and legacy of Kim Wood, one of the most influential figures in the history of strength training.

Kim Wood was the NFL’s first full-time strength and conditioning coach, serving the Cincinnati Bengals for nearly three decades and helping shape how professional athletes train to this day. Long before strength training was widely accepted in professional sports, Kim was pioneering methods focused on strength training, discipline, and long-term athlete development.

Luke and Rick share personal stories and firsthand experiences with Kim, discussing his mentorship, his larger-than-life presence in the weight room, and the profound impact he had on their careers and perspectives on training. The conversation highlights not only Kim’s contributions to professional football, but also the values he instilled—work ethic, humility, and respect for the process.

This episode serves as a tribute to a true pioneer whose influence continues to be felt throughout the strength training industry.
