Abdominal muscles (Abs) provide support to maintain posture and participate in breathing process especially during exhale (when they help force air out of the lungs by depressing the thorax).
When exercised they can be defined by the 6-pack ab effect (Rectus Abdominis). The deeper muscles (close to the spine) have the most effect on posture and help to maintain a healthy back (Transverse Abdominis).
The Oblique muscles that run along the sides of the torso/trunk (external & internal) work to rotate the trunk/torso and (bend) flex the spine, along with maintaining posture.
You do not need to go to the gym or need much equipment to exercise the Abs. Described below are a few routines that, when consistently practiced, will work and build these muscles.
