Low Back Hurt?
This is a great stretch that can be done without getting down on the floor. There are many stretches for the low back. This is stretch actually for the psoas muscle (see the video).
When the psoas is tight – which it is on the majority of people, it makes the low back muscles work harder, get knots, and be painful.
The psoas muscle shortens when people spend a lot of time sitting – even in exercises where you are not erect – such bike riding, kayaking, rowing, etc.
