Whether a person's body is strong or not is related to the strength of the kidney. When winter comes, the human body needs enough energy and heat to protect itself. If the renal function is weak, it will cause dizziness, palpitation, shortness of breath, weakness of waist and knees, fatigue, urinary incontinence or urinary incontinence due to "insufficient firepower", which is kidney-yang deficiency. There are also people with insufficient body fluid, and the function of moistening and nourishing is reduced. The clinical manifestations are emaciation, soreness of waist and knees, dizziness and tinnitus, dry mouth and throat, hot flashes, cheekbones, night sweats, short and yellow urine and so on. This is kidney yin deficiency.

There are many ways to nourish kidney and tonify deficiency. For example, bask in the sun more, eat more foods with high calorie and warm kidney yang, take drugs for tonifying kidney and so on. However, starting from the basic theory that "life lies in exercise", it is a positive measure to tonify the kidney and strengthen the body through exercise. Here are four yoga poses that can strengthen the waist and kidney: windmill, inverted triangle, eagle claw sitting, one-legged V-shape and standing at right angles.
