If you spend a lot of time bent over a computer or device or are just worried about your posture, you’re going to love this easy video. It offers 4 minutes of simple exercises designed to combat a forward posture slump and prevent that little hump on your back that’s also known as a dowager’s hump or buffalo hump.

In this video, I was introduced to the YWTL exercise. This simple flow of arm positions is named after the shapes your arms make while doing the easy movements. I could immediately feel the difference in my back and neck when I ran through the sequence.
