Why Exercise Matters More Than Ever in 2025
Regular physical activity is the foundation of both physical and mental health. In Korea, over half of adults and more than 90% of adolescents are not active enough, leading to increased rates of obesity, hypertension, and chronic disease. Globally, the fitness industry is shifting from “just getting in shape” to optimizing longevity, flexibility, and mental wellness. Exercise isn’t just about appearance—it’s about building a resilient, energetic, and balanced life.
