When lifting heavy objects, bend the hips and knees, squat down, straighten the waist and back, and press the heavy objects tightly on the body before you can stand up and step. 2. Do not sit, stand or work at the desk for too long. Avoid the soft tissue fatigue caused by keeping a posture for a long time.
