The external oblique abdominal muscle (Musculus obliquus externus abdominis) is a quadrilateral, approximately 0.7 cm thick plate. It is the largest of all abdominal muscles and is the most superficial. Training this muscle group makes sense not only for aesthetic reasons, but also for health reasons.
Here you will find detailed information about abdominal muscle trainingApproach: inguinal ligament, labium externum of the crista iliaca, tuberculum pubicum Origin: outer surface of the 5th – 12th rib Innervation: Nn. intercostales V- XIIIn accordance with the function of this muscle, the oblique abdominal muscles contract when the upper body is rotated and the upper body is tilted sideways. In abdominal crunch, the effect on the external oblique abdominal muscle can be increased by turning the upper body sideways during contraction. The following exercises are therefore particularly suitable: An overview of all relevant topics in the field of strength training can be found in the overview strength training
- Lateral push-ups
- Abdominal crunch
If the upper body is tilted or turned to one side, the opposite oblique abdominal muscles are stretched at the same time. Note: If the outer oblique abdominal muscle is stretched, the inner oblique abdominal muscles are stretched and vice versa.
The function of the external oblique abdominal muscle (Musculus obliquus externus abdominis) is to incline the axial skeleton. One side of the external oblique abdominal muscles works together with the internal oblique abdominal muscles of the opposite side. In addition, the external oblique abdominal muscle supports the straight abdominal muscle in straightening the upper body.
