Mike Boyle on Thoracic Mobility vs. Rotary Strength: What You're Getting Wrong

In this episode of The Strength Coach Podcast, host Anthony Renner sits down with renowned strength coach Mike Boyle to dissect the critical distinction between thoracic spine mobility and rotary strength—a topic that has sparked debate online. Boyle critiques the tendency of some fitness influencers to make false comparisons between mobility drills and strength exercises, arguing that such comparisons are misleading and manipulative. He emphasizes that both types of training have value when used appropriately: mobility work in warmups and strength training in performance sessions. The conversation expands into broader themes of training for results over training for the sake of training, advocating for a focus on measurable outcomes like improved speed, power, and injury resilience. Boyle also discusses the importance of tempo and eccentric control, while cautioning against overcomplicating programs with excessive volume or overly rigid protocols. He shares insights on program design, including how to tailor training to sport-specific needs—such as prioritizing hip and groin work for hockey players or rotator cuff stability for baseball players—while maintaining foundational movement patterns. The episode closes with reflections on the role of isometrics and slow-tempo training in joint health and injury prevention, especially for older clients.
