A #strong#core distributes the #stresses of #weight-bearing and protects the #back.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. When this happens, we are able to generate powerful movements of the extremities.The core muscles also make it possible to stand upright and move on two feet. These muscles help control movements, transfer energy, shift body weight and move in any direction. A strong core distributes the stresses of weight-bearing and protects the back. Core conditioning exercise programs need to target all these #muscle groups to be effective.
