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.
