Starting a treadmill diet is easy, but maintaining it is hard. I felt dizzy and lightheaded too. In Traditional Korean Medicine (TKM), obesity is not simply a matter of excess calories but an imbalance of body functions. It is often seen as an accumulation of phlegm-fluid (痰飮) due to Spleen deficiency (脾虛), where digestive and absorptive functions are excessive while metabolism is impaired. Treadmill exercise is an excellent supplementary method to resolve this phlegm. Here is a checklist: 1) Regulating Qi (氣) comes first. Heart rate is more important than speed. Maintain a pace where you can talk for at least 20 minutes. This steady heartbeat improves blood circulation and alleviates blood stasis (瘀血). 2) Post-meal exercise aids digestion. TKM recommends light exercise after eating to support the Spleen's transportation and transformation (脾氣運化). The ideal time is 30–60 minutes after a meal. 3) Adjust intensity according to your body type: for beginners, brisk walking (5–6 km/h); for moderate fitness, slow jogging (7–8 km/h); for experienced, interval sprints. 4) Replenish fluids after exercise without adding sugar. Heavy sweating may deplete Qi and Yin (氣陰). Warm water or nourishing health drinks are recommended. However, overdoing it may strain joints or worsen high blood pressure. Those with hip or knee pain should consult a TKM practitioner for a personalized exercise prescription based on constitution and body type.
