This method has helped people have a strong body and well defined abdomen. However, some are still skeptical about the effectiveness of the method.

This exercise is excellent for the central part of the body. It helps define the muscles of the legs, arms, buttocks, abdomen and back. It eliminates deposits of fat as well.

This exercise is the plank exercise. The challenge lasts for 4 weeks and the difficulty of the exercise increases gradually. In the beginning, the plank lasts for 20 seconds and at the end for 4 minutes. As the strength of the muscles increases through the weeks, so does the resistance of the body.

The exercise must be done in the right way. First get in the plank position and support the body on the toes, arms and hands. Raise the upper part of your body and remain in a straight position.

The best time to do this exercise is in the morning.
