In Columbus, it’s easy to buy into the glow of a red light sauna quick, shiny, and effortless. But if your knees ache on Short North sidewalks, your shoulders round at a downtown desk, or your hips lock up on the golf course, the sauna won’t fix it. Corrective exercise will. It takes work, yes, but that work rewires how you move, eases pain, and keeps you active for years instead of weeks.
