I remember when I first started walking; I was so out of shape that I felt dizzy and breathless. If you let your ambition outpace your physical state, you risk injuring your joints while metabolic waste known as Phlegm-fluid (Dameum) remains trapped in the body. Here is a step-by-step guide to walking for successful weight loss: 1. Check for Dampness-Phlegm (Seup-dam): If your body feels heavy or swells easily, walk slowly at first. When waste products block the body's pathways, energy cannot be consumed efficiently. 2. Support Spleen-Qi (Bi-gi) with posture: People with Spleen-deficiency (Bi-heo) often have a hunched posture. Keeping your chest open and your core slightly engaged allows your vital energy to circulate better. 3. Use interval walking for Qi and Blood (Gi-hyeol) circulation: I recommend an interval method—strolling for 5 minutes and walking briskly for 3 minutes. This is highly effective for clearing Blood Stasis (Eo-hyeol), which is essentially 'stagnant' blood. 4. Mindful breathing and hydration: After walking, soothe your thirst with lukewarm water rather than gulping down ice-cold water, which can shock your internal systems. Finding a pace that suits your individual Constitution (Che-jil) is more important than blindly following others. In my experience, the most efficient path is to identify your current level of Phlegm-fluid at the clinic and set a customized exercise intensity that matches your body's needs.
