Q. I want to lose weight using a treadmill; what is the most effective way to use it?

I have personally experienced the mistake of pushing myself too hard through intense running, only to end up with knee pain and burnout. It is a common misconception that sweating more always equals better results. From the perspective of Traditional Korean Medicine (TKM), every individual has a different efficiency in utilizing energy. Those with robust digestive functions and abundant energy are well-suited for interval training, which boosts metabolism by alternating between fast sprinting and slow walking. On the other hand, individuals with a 'Spleen Deficiency (Bi-heo, 脾虛)'—characterized by poor digestion and chronic fatigue—must be cautious. For this type, excessive exertion can further deplete their 'Qi' (vital energy) and exacerbate 'Phlegm-Fluid (Dameum, 痰飮)' accumulation, leaving the body feeling heavier and more lethargic. In such cases, walking at a slight incline is far more efficient. Furthermore, for those with 'Blood Stasis (Eo-hyeol, 瘀血)'—where blood circulation is impaired—it is crucial to prioritize stretching and light aerobic activity to wake up the blood flow before attempting high-intensity workouts. Ultimately, the priority is determining whether your body is currently in a 'state capable of running.' Finding the exercise intensity that matches your constitution and current condition is the fastest route to success. If you are unsure of your current state, I invite you to visit the clinic for a professional consultation.
