Agood posture is one that places the least amount of on your muscles and joints. a. pain b. pressure c. stress d. flexibility

B. Pressure; as in any pressure that you place on any body part, mainly your spine, may or may not eventually be impacted negatively, as such, you may not want to be slouched over for long periods of time because that's bad posture and will impact the way you walk and stand. But not being slouched over does the opposite affect and places no pressure on bones, ligaments, muscles, and joints, and will not impact the way you walk. Remember to check yourself.
Hope this helps! :)
