How do you loosen a tight lower back?
How do you loosen a tight lower back? Lie on your back flat on the floor with your knees bent. Lift your hips and place a firm cushion or foam roller underneath. Completely relax your body into the floor and into the foam roller/cushion. Hold this pose for 30 to 60 seconds, and repeat the stretch 3 to 5 times, resting 30 to 60 seconds between each set.
