Sit-ups are a common way to exercise your abdominal muscles. For people who are constantly exercising and having a muscular back, moderate sit-ups have a good effect on enhancing the toughness of the lumbar and cervical muscle groups.
However, sedentary office workers are not suitable for sit-ups. Because the sedentary movement for a long time, especially the posture of bowing and bending, the neck and lumbar vertebrae have been subjected to greater pressure. At this time, doing sit-ups will cause the cervical vertebrae and lumbar vertebrae, which have been "injured", to be oppressed again, which will increase the degree of damage.
A set of sit-ups in place requires repeated bending and bending of the neck, and the back muscles are heavily loaded. This is tantamount to a person who has suffered from long-term back pain because of sedentary; more importantly, under normal conditions. The lumbar vertebrae are convex forward, and the lumbar intervertebral disc has a thick leading edge and a thin trailing edge. When doing a sit-up such as sit-ups, the lumbar intervertebral space is narrowed and the trailing edge is widened, which increases the posterior pressure of the intervertebral disc. Repeating the waist for a long time can cause the disc to protrude backwards, compressing the nerves, causing pain in the lower back and lower limbs.
For sedentary people who want to exercise properly, prevent cervical spondylosis and lumbar spondylosis, try these simple stretching exercises:
1. Put the legs on the chair, stretch the back muscles, and stretch the hands backwards to make the chest expand;
2. Maintain a sitting position, straighten your feet and do a forward flexion exercise;
3. Maintain the cross-legged posture, first straighten the right leg, bend forward, bend the right toe as much as possible, hold for 10~20 seconds; then change the left leg. The same way can be exchanged for 2~3 times.
