Treadmill exercise may seem simple, but lasting results require considering the body's qi and blood circulation and spleen–stomach function. If you have a spleen deficiency constitution, energy production may be poor, leading to extreme fatigue after exercise or even a surge in appetite. At our clinic, we view the first 1–2 weeks as an adaptation period: we check your current phlegm-fluid and blood stasis levels through pulse and tongue diagnosis, then guide you to walk briskly (4–5 km/h) for 20–30 minutes to acclimate the body. Weeks 3–4 are the main phase: increase incline to 3–5% and speed to 6–7 km/h, mixing in 1–2 minutes of jogging intermittently. During this time, opening the stomach and spleen meridians with acupuncture or herbal acupuncture can boost fat-metabolizing enzyme activity, as clinical reports suggest. Months 1–2 are the stabilization phase: maintain a steady exercise intensity while reinforcing the spleen and addressing damp-phlegm with herbal medicine, which speeds recovery and reduces rebound weight gain. Since individual response varies, personalized guidance from a Korean medicine doctor is key to adjusting intensity, duration, and incline without overexertion.
