人体最累的不是腿,而是腰。虽然每天走路要用到腿,但坐下时腿已经休息了,腰还在支撑着体重。只有在平躺时,腰承载的压力最小。由于有些人坐姿不对,长时间坐办公室、开车、坐沙发、看书或上网工作、应酬吃饭……久坐伤腰,腰椎间盘承载的压力最大。 The body is not the most tired legs, but the waist. Although the legs used to walk every day, but the legs have been resting when sitting down, the waist is still supporting the weight. Only when lying down, lumbar pressure is minimal. As some people sitting position, sit in the office for a long time, driving, sitting sofa, reading or Internet work, entertainment dinner ... ... sedentary waist, lumbar disc bearing the greatest pressure.
