When you spend over two decades watching bodies move under pressure, your eyes just naturally pick up the subtle details. I was recently looking at a training clip of elite ultrarunner working with her coach on a loaded lateral lunge variation. Even in a lightning-fast sequence where the movement flashes by in seconds, I caught a mechanical leak right away: as soon as she bumped up the weight, her upper back started rounding, and she lost that vertical stack. The coach actually rolled with it and kept the session flowing, which is totally fine - when you’re managing high-mileage recovery and tissue resilience mid-season, sometimes keeping the momentum going is the priority. This isn’t a critique of the coach at all. Every coach has their style and priorities in a session. But it highlights why having a sharp eye for body mechanics matters so much. Before I became a certified personal trainer through the American College of Sports Medicine, I spent years teaching martial arts - identifying, correcting, and instructing students in complex striking mechanics long before stepping onto a traditional gym floor. That background trained me to spot micro-compensations, shifting centers of gravity, and kinetic leaks instantly, whether someone is throwing a strike or moving under a load. If you’re unsure about your own mechanics in the squat, lunge, running and especially striking. DM and let’s chat. #posture #coach #fitness
