These bones are arranged in three natural curves that are necessary to keep your body supported. Strong, flexible muscles help maintain these curves. This condition is called lumbar lordosis. Too much of a curve in the low back puts pressure on the entire back. This can lead to pain and poor movement.
Good posture is necessary to keep the curves in their proper positions.
Strong, flexible muscles help maintain these curves. Weak and stretched out muscles cannot give our spine adequate support for good posture. Practice good posture while standing and especially while sitting. Support the lower curve in your back with a pillow. Too much or too little of a curve can cause problems.
