If your lower back just feels tight how can you pop it?

Answer 1

Lie on your back on a flat surface. Bring one of your legs up towards your chest, with your knee bent, and, while keeping your upper body on the floor, rotate your knee across your body, reaching for the floor. You can push your knee towards the ground to help, but not too much- you'll just hurt your back. Do this to your other knee.

Answer 2

That's not always a good idea, especially if there has been damage. Lower back problems can lead to serious, permanent damage.
