Why Core Control Is the Secret to Better Turns and Tricks

What does “core tension” really mean—and how does it impact your skiing and riding? In this episode of First Chair, George Thomas talks with PSIA-AASI National Team member Tony Macri about how core engagement drives balance, stability, and performance across all disciplines. Based on his 32 Degrees article, Tony breaks down how the core goes beyond just your abs, how different types of muscle contractions (concentric, eccentric, isometric) come into play, and how concepts like timing, intensity, rate, and duration shape movement outcomes. From freestyle tricks to carving and riding variable terrain, this episode offers practical ways to use your core more effectively—without overthinking or over-tensing. 00:00 Intro + Meet Tony Macri 00:21 What Is Core Tension (Beyond Abs)? 00:48 Core Engagement vs Tension Explained 01:30 Types of Muscle Contractions (Concentric, Eccentric, Isometric) 02:59 When to Engage vs Relax the Core 03:40 DIRT/TURD: Timing, Intensity, Rate, Duration 06:12 Why Timing Matters Most 07:05 Applying Core + Movement Without Overthinking 08:39 Teaching Progressions: Breaking It Down 10:26 “Prepare for a Punch” Cue Explained 11:59 Why Core Control Matters in 360s 13:11 Core Strength and Off-Snow Training 14:22 Whole Body Fitness + Core Work 15:41 Core Use Across All Disciplines 15:53 Balance Drill: Eyes Closed + Board Movement 17:16 Teaching Core from Day One 18:18 Final Takeaways: Balance, Flow, and Control
