It is often simpler and simpler, but the difficulty will never decrease. Sit-ups are 10, which is easy and common, but it requires a lot of core strength, so it is often called comparison action to let me do it. First of all, sit-ups rely on the waist and abdomen, so they need to have a strong core strength. Some people's abdominal strength is not good enough, that is, their core strength can't keep up, but this action is extremely difficult for these people.

You will often see that when you go to physical education class, many physical education class will do this kind of exercise, requiring only 50 or even 50 nonstandard sit-ups to complete a course. For girls, even many people can't really complete a standard sit-up, which requires too much core strength. Some are heavier and can't even do sit-ups. This is a very common question.

Moreover, sit-ups not only exercise abdominal muscles, but also exercise the coordination and muscles of the whole body. Moreover, if sit-ups are not standardized, they may hurt your waist, which has confirmed your problem, so this fitness work is 10, which has some minor hazards. For people with poor core strength, it is not recommended to do a lot of sit-ups for fitness.

Although the effect of sit-ups is very good, not everyone is suitable for this kind of exercise, because his physical requirements are really not low. A standard sit-up, for some ordinary people, is difficult to complete correctly, or the strength is right. Therefore, more than 70% people only use strength to complete a standard sit-up, especially the head-holding action, and often use part of their arms to complete a sit-up.

I also think that sit-ups are not easy and simple movements, and it is actually more difficult to complete a standard movement by waist and abdomen strength.
