Extended information sit-ups can reduce stomach, but the effect is slow, and weight loss must be done slowly. Fat energy in the body needs at least 20 minutes of exercise to be used and burned.

But now many people have small stomachs and often can't find time to do outdoor sports, so they choose to do sit-ups at home to reduce their stomachs. And force yourself to complete how many movements in one minute, thinking that this can strengthen the abdomen.

In fact, too fast frequency can't improve the effect of exercise. Only by slowing down the pace of exercise properly can we avoid affecting the body and enhance the effect of reducing stomach. At the same time, experts remind that many practitioners' sit-ups are incorrect. If the posture is not correct, the training effect will often be different.
