Holding the human body upright takes energy, and muscles use energy. Our muscles are constantly working and holding us up as we stand, sit, lie, or move. These muscles make many adjustments every second so that our movement and stance is fluid.

Have you ever seen a cheetah run on TV? Its whole body moves in perfect coordination and balance without the cheetah having to consciously think about it. The same goes for us humans. Good posture is not a simple alignment of body parts like toy blocks; rather, it is a dynamic - always changing and adjusting - interaction between us and gravity. With good posture, our body works efficiently by spending less energy to counteract with gravity.

Everything we do is affected by gravity. The shape of our bones is determined by the forces of gravity as well as our posture, which determines how we react to gravity. Simply stated, your posture influences the shape of your skeleton! This is why a rehabilitation team is always checking your posture as you walk, sit, and stand.

Maintaining proper posture is especially important in preventing secondary injuries and flare-ups. Strong, flexible muscles are essential because they support the spinal column and other joints, which are the framework for correct posture.
