A

Has 2 proximal heads

Proximal unattached to the medial and lateral epicondyles of the distal femur

160
Q

168
Q

Rectus abdominus

A

Paired midline muscles

Powerful flexor of the anterior abdominal wall
Strengthening of the abdominal muscles is a very important part of the back therapy, because the abdominals, act support the back

Mid portion of the belly

When this is well developed it becomes a 6 pack

Main purpose is to cause trunk flexion
Must be supine (sit up position) to get trunk flexion because if you are standing the lower back is doing the work
