I spent a decade getting strong in the gym—building baseline strength, joint tolerance, and the kind of discipline that comes from showing up for the same work over and over. And I’m not here to trash the gym. The gym is powerful because it’s controlled: stable temperatures, predictable surfaces, clean reps, measurable progression. For trail runners and ultra athletes, that control is a tool—especially when you’re trying to bulletproof connective tissue and build strength that supports more running. But the strongest version of me didn’t show up until I stepped outside. In the mountains, nothing is symmetrical and nothing is guaranteed. Outdoors you train adaptation, variability, and resilience under uncertainty—foot placement changes, grades change, weather changes, and your body has to solve problems in real time. In this video I break down why both environments matter, and how outdoor training translates into real-world movement that actually shows up on trails and in ultras. If you want strength that carries over to uneven terrain and long days, you need the gym for the base—and the outdoors for the chaos.
