rectus abdominis
flexes vertebral column
Rectus abdominis is a paired muscle that runs vertically along the anterior (front) wall of the abdomen. It is commonly referred to as the “six-pack” muscle due to its shape. Rectus abdominis is responsible for flexing (bending forward) the trunk at the waist and compressing the abdominal contents.
In addition to its role in trunk flexion and compression, rectus abdominis also plays a role in maintaining posture and stability of the lumbar spine. It is involved in movements such as sit-ups and crunches, as well as in exercises such as planks and abdominal bracing.
Rectus abdominis can be strengthened through a variety of exercises, including sit-ups, crunches, leg raises, and planks. It is important to note that proper form and technique are crucial when performing these exercises in order to avoid injury and ensure effectiveness.
Overall, rectus abdominis is an important muscle for core stability and spinal support, and can be targeted through specific exercises to help improve overall strength and posture.
