Crunches or sit-up is perhaps the best known abdominal exercise. However, this exercise is said to be not as effective as plank.

Plank is a excercise that requires a person to place both sides of hands, including elbows, on the ground, then put other parts of the body as if push-ups gesture. Men or women can do it, with the same posture.

Generally, plank looks easy to do. Yet, when you try it, stomach will feel being pressed. This condition indicates that the muscles are "reacting" to the excercise.

There are many benefits of plank for body. Not only does the abdomen benefitted from plank, but it also benefits the entire body.

1. Improve Posture
2. Practicing body balance
3. Train Flexibilitàs
4. Helps Body Metabolism
5. Lowering the Risk of Back Injury
6. Flatten the stomach
The longer you are able to hold the plank position, the better the benefits. The main key so that you can hold the plank longer is to do it gradually every day. Do not force it to do it directly for a long time.
In addition to duration and consistency, pay attention to basic plank techniques so that the effort doesn't go to waste.
