For those whose jobs require them to stand on their feet, a simple stretch can cut the risk for back pain by as much as a third. In this study, participants stood for two hours in two sessions one week apart. During one of the two sessions, they bent all the way forwards for five seconds every 15 minutes. During the other session, they refrained from any stretching. The participants were 36% less likely to report back pain following the session that included the forward-bending stretches than when they stood still for two hours.
