《资治通鉴·汉纪·汉纪十六》
休息的时候，作些俯仰屈伸的动作以利于形体，用散步、小跑等运动来充实下肢；吸进新鲜空气，吐出腹中浊气以锻炼五脏；专心专意，积聚精力，以调和心神。用这样的方法进行养生，怎能不长寿呢！
休则俛仰屈伸以利形，进退步趋以实下，吸新吐故以练臧，专意积精以适神，于以养生，岂不长哉！
During breaks, do some stretching and bending exercises to benefit your body, and do sports such as walking and jogging to strengthen your lower limbs; inhale fresh air and exhale turbid air from your abdomen to exercise your internal organs; be focused and attentive, and accumulate energy to harmonize your mind and spirit. How can you not live a long life by using this method to maintain your health!
