Dynamic posture is how you hold yourself when you are moving, like when you are walking, running, or bending over to pick up something. Static posture is how you hold yourself when you are not moving, such as when you are sitting, standing, or sleeping. Knowing what proper posture is and consciously being aware of your own posture takes time and usually some guidance. Proper posture training involves the core muscles, so you are essentially pre-programming all of the muscles in your body to provide stability and produce motion.
