Do sit-ups build muscle?

When it comes to sit-ups, we are all familiar with them. Many people have done sit-ups. Now primary school students should have this kind of fitness exercise in their physical education classes. Doing sit-ups every day has a good exercise effect on the muscles of the body. When doing sit-ups, we must pay attention to the correct posture. Today we will see if sit-ups will exercise muscles and which muscles will be exercised?

The abdominal muscle group mainly includes: rectus abdominis, external oblique muscles, internal oblique muscles, iliopsoas muscles, etc. Traditional sit-ups mainly train the rectus abdominis. Muscles have two ends, and when they move they contract with one end as a fixed point. According to the upper and lower relationship, it can be divided into upper fixed and lower fixed. Taking the rectus abdominis as an example, the upper end is attached to the sternum and ribs, and the lower end is on the pelvis.

Therefore, lower fixation refers to the situation where the pelvis is used as a fixed point during contraction. Generally speaking, the muscle training intensity at the fixed end is relatively greater. Traditional sit-ups are fixed at the bottom. If you want to exercise the upper fixation of the rectus abdominis, you can try doing straight knee leg raises. To exercise your external oblique muscles, you can try the side-lying get-up exercise.

In addition, the iliopsoas muscle is relatively hidden and requires increased exercise to exercise it. Fitness coaches believe that if you want to make sit-ups more effective, for middle-aged men and women who mainly train lower abdominal fat, appropriate knee-bending and leg-lifting exercises can more effectively train the lower abdominal muscles and achieve the goal of training the abdominal (upper and lower abdominal) muscles.

The above is what we learned today about which muscles are exercised by sit-ups. In daily life, we can do sit-ups in moderation every day. It not only exercises muscles, but also helps lose weight. Especially for people with fat in the lower abdomen, it is very effective for weight loss. Another thing to note is that when doing sit-ups, don't rise and fall too fast to avoid damage to the bones.
