Exercises affecting the muscles in the front of the abdomen (belly). also called abdominal or stomach muscles, ab and abs. Abdominal muscles, together with muscles in the back, make up 'core' muscles, supporting the trunk, keeping body stable and balanced, protecting the spine, assisting in the regular breathing movement and keeping abdominal organs such as the intestines in place. These muscles tend to weaken with age unless specifically exercised. Strong back and abdominal muscles can help heal most types of back pain, enhance balance, improve posture, reduce scoliosis symptoms, help prevent falls and injuries during sports or other activities. Causes of abdominal muscle strains include overstretching, overuse or a violent, poorly performed movement of the trunk.
