Back-assist exosuits might let workers lift heavier and longer without wrecking their backs.

Other research shows that when people wear these back suits, their muscles don’t have to work as hard during lifts, which means they can keep going longer without feeling wiped out. Workers in small tests reported feeling less strain and said they’d want to use them on the job. Some studies even found that the suits reduced pressure on the spine, which could mean fewer injuries over time. But it’s worth noting that none of this comes from the study linked in the post — all the evidence comes from other research that’s promising but not yet definitive in real-world settings.
