The abdominal muscles are considered to be part of the trunk or core muscles of the body. The core muscles are used in almost every activity you engage in each day. The strength of your core muscles will affect your ability to perform everyday activities. In addition, your abdominal strength affects your posture. Poor posture is considered a common cause for lower back pain.
By improving your abdominal strength, the abdominal muscles will bear more of the physical burden required to perform your daily activities. This will alleviate undue stress placed on your lower back muscles. Abdominal exercises will also help improve your posture. Better posture will align your body and alleviate back pain frequently attributed to poor posture.
