When the core muscles are weak or there’s an imbalance (for example when you only carry out sit ups and the back is thus weakened), a common side effect is back pain.
Core strength refers to the muscles of your abs and back and their ability to support your spine and keep your body stable and balanced. The core muscles help control movements, transfer energy, shift body weight and move in any direction plus can heighten sporting performance when strong. The best core exercises may surprise you. It’s not enough to just do ab crunches and sit ups. To build a strong core you need to exercise a variety of muscles from your hips to your shoulders.
Most people think of the core as a nice six-pack, or strong, toned abs, but the truth is that the abdominal muscles are a very small part of the core. The abs have very limited and specific action, and what experts refer to as the “core” actually consists of many different muscles that stabilize the spine and pelvis, and run the entire length of the torso. When these muscles contract, they stabilize the spine, pelvis and shoulder girdle and create a solid base of support.
