It takes a good amount of conscious effort to just SIT with good posture.
How are you sitting right now, did you just adjust yourself? Is or was your posture slumped? What is your abdominals doing? Are they relaxed, is your belly sticking out, possibly a few rolls?
Seated in a hunched position, with your shoulders protruding forward, back rounded and core relaxed at the computer desk or looking down at your phone over time increases the risk of injury or pain placing considerable tension on the neck, shoulders and back.
Ever had a sore back for sitting too long at your computer?
Try sitting up nice and tall, your belly will instantly flatten out and you will see that in order for you to continue to sit up tall you need a fair amount of abdominal and back endurance to maintain a good seated posture. There should be a slight inward curve in your back with your ears directly over your shoulders. With good posture the body’s alignment is balanced and the pressures and tension acting upon supporting structures (ligaments, tendons and cartilage) are minimal.
Benefits of a strong core includes:
Improves Athletic Performance:
The muscles of the trunk and torso stabilize the spine from the pelvis to the neck and shoulder, allowing the transfer of power to the arms and legs. All powerful movements originate from the centre of the body out, and never from the limbs alone. Before any powerful, rapid muscle contractions can occur in the extremities, the spine must be solid and stable, and the more stable the core, the more powerful the extremities can contract.
