Posture improvement by conducting a set of stretch protocols with an inelastic strap which lengthen front torso muscles in order to reduce forward head position, and to decrease rounded shoulders. Posture improvement is monitored by periodically taking hip to rib, sternum to shoulder, and shoulder to shoulder measurements. The protocols may be performed at home, or in groups such as company sponsored activity. The strap may include markings to permit a participant to readily determine desired hand positions on the strap for a stretch protocol.
