Abs area is very important for the look. Maybe you are slim, but you don’t feel satisfied because you have an abdomen that is not flat. You feel that you are fat, only for the posture that you think like pear or apple in the abs area. So, I think it is time to practice abdominal exercise, to get the flatter abs.

The crunches, which works the short abdominal, and the sit-ups that exercise the long, are classic exercises present in all training. They usually associate for a more complete result. The sit-ups, in which, with the legs flexed, the entire torso is raised and lowered, taking off the entire back of the floor, is an exercise that involves several muscles at once. It works more than one joint in addition to the musculature: when it rises, the hips do it and the lumbar area also intervene.

It is a strength exercise that trains the entire muscle block but requires certain precautions. It demands a certain general strength so as not to do it badly. It can be done in several stages: the first is the little ball exercise that is done, in which they raise their torso with their legs and arms outstretched. The different variants of the exercise have to do with the level of training. The first is the little ball exercise.

The short abdominal is a localized exercise that prevents the abdomen from going forward. They are done with the legs bent, with the pear off the chest, the hands on the nape of the neck, the elbows wide open and the back well supported. Without strength with the neck or shoulders, head and shoulders rise and fall, keeping the waist well supported. Like any exercise, although it is simple, it requires certain precautions. You have to be careful with the neck to avoid making force with it, to avoid it, it is important to have your hands on the nape of the neck, the elbows open, the pear detached from the chest when going up, and the crunches have very little possibility of injury.

The most advanced add repetitions: 50 to 100 of crunches, 15 to 30 of sit-ups and more than a minute of planks and a good diet, an indispensable ally to achieve good abdominals.
