As a practitioner, I also have days when my legs feel swollen and my body heavy, and I completely understand the struggle of knowing you 'should' exercise but finding it impossible to start. First, let me explain the benefits of Traditional Korean Medicine (TKM). Our herbal prescriptions are designed to increase your basal metabolic rate even without exercise. Specifically, they help eliminate 'Dameum' (痰飮)—a TKM concept referring to the accumulation of metabolic waste and fluid stagnation—which improves circulation and suppresses 'false hunger,' making dietary control significantly easier. However, there are realistic limitations. Losing weight without exercise often leads to a decrease in muscle mass. This can lower your metabolic rate further, increasing the likelihood of the 'yo-yo effect' where weight is easily regained. Additionally, you miss out on the psychological stress relief and the joy of physical activity. Ultimately, the approach depends on your specific constitution and current health status. For those with severe 'Bi-heo' (脾虛)—a deficiency in the Spleen/digestive system leading to insufficient energy production—it may actually be more appropriate to first restore vitality and stabilize metabolism with herbal medicine before attempting strenuous exercise. I suggest we first evaluate whether your body is currently in a condition that can safely handle exercise.
