To relieve lower back pain, stretch the front of your hips daily (or every other day).
Hip Flexors: You need to do this stretch, particularly if you sit all day at work. Sitting all day puts pressure on the hip flexor muscles. This is a major cause of minor low back pain. Stretching your hip flexors muscles several times a week will prevent this kind of lower back pain.
How To: Stand in a modified runner stance, with right foot forward and left foot back, feet flat on floor. Put your hands on your hips and keep your back and hips in straight alignment. Push forward with your hips, while maintaining your erect posture. Slowly, push your hips forward only until you feel a comfortable level of tension. Hold for a 10 count. Switch sides by reversing your leg stance and repeat.
