As the core has a weight-bearing function for your lower back, when the core is weak, you are more likely to experience back pain and back problems. Training your core improves your core stabilizers which act to support muscle action by providing a rigid base of support for movement. With a strong core, your back is better able to manage long days spent sitting (at your desk, in your car or on a plane).
Core stability is provided by muscles in the torso that connect the spine, rib cage and pelvis. When standing, the pelvis and lumbar spine are oriented for maximal stability. The goal of training your core is to maintain this ‘neutral spine’ orientation throughout dynamic movement. Stabilizing exercises are ones that groove motor patterns and ensure a stable spine during activity.
To improve your core, focus on progressive exercise that emphasizes muscle contraction with the spine in a neutral position. The spine’s posture determines the interplay between ligament and muscle forces.
