Nest in the sofa. Soft sofas can make people's hips sink and their bodies nest up, which makes them feel very comfortable. However, because the knees are higher than the waist, the back is arched, and the waist muscles will be pulled, so the burden will be great, and the sedentary waist muscles are easy to fatigue, causing low back pain. It is better to have a hard chair, especially for people with bad waist, which is not suitable for sitting on soft sofas or beds.

This chair is only half full. Some people are used to sitting with their hips just next to the chair, with their backs on the back of the chair, their waists dangling and their legs stretched out. In fact, this seemingly comfortable sitting posture does great harm to their waist. This is because this sitting posture makes the spine arch and the waist loses the support of the chair back, so the pressure will be great and it will easily cause low back pain. It is recommended that when sitting, make sure your hips are on the chair and your whole back is close to the back of the chair.

Sit cross-legged Many people like to sit cross-legged or put one foot on the other. But over time, it will cause muscle imbalance on the left and right sides of the leg, which will affect the waist muscles. It is recommended to sit with your legs flat on the ground and your thighs parallel to the ground. If the chair is too high, you can put a small bench under your feet.

Lean forward. Some people are used to leaning forward when sitting in order to see the computer screen clearly, which will also hurt their waist. Many people also have the habit of leaning forward when driving. In fact, in the case of wearing a seat belt, the tension at the waist is great. The correct sitting posture is that the waist is close to the back of the chair and the back is straight.
