Why people use a back stretcher
After a day at a desk or behind the wheel, the lower back often feels compressed and tight. Lying over a gentle curve lets it open up again. It's simple, quiet and takes just a few minutes.
Hard plastic boards can feel uncomfortable at first, especially for beginners and older adults. That's why many people choose a softer, heated option. Read about lumbar traction at home to understand the idea behind it.
What is a back stretcher?
A back stretcher (also called a lumbar stretcher or back cracker board) is a curved support you lie on. Its arch gently opens up the lower back. Many people use one after long days at a desk or behind the wheel.
