A trainer says this five-minute mobility routine will improve your posture—so I put it to the test

A woman in a sports vest holds a resistance band taut in her hands, with her arms straight. She is smiling. Behind her we see a bookcase, lamp and wooden flooring.

I spend 90% of my working day sitting at a desk, usually hunched over my laptop in deep concentration. I've tried to change my posture and improve my at-home office setup, but I usually end the day with a lot of upper-body tension and a severe knot in my right shoulder.

One of the only things that provides immediate relief is stretching, which is why I was happy to see this mobility routine from trainer Elizabeth King on Instagram. It's a five-minute session designed to correct rounded shoulders, targeted at desk workers like me.
