Posture Posture Posture

There is a reason I posted this video, being posture.  Many people struggle maintaining proper posture when standing or sitting.  So this video explains how one should stand.  Try doing it when standing in line at the bank or grocery store.  Seems silly but you are working your abdominals and back, which for those who complain about back pain this is a simple and easy exercise to perform and strengthen those intrinsic muscles of the spine.
