If you have had persistent lower back pain, begin by consulting a competent orthopedic. Chances are that your problem is related to your lifestyle and a lack of back and core exercises. Your doctor will most likely put you on a physical therapy course. The good news is that if you do the physical therapy religiously, and then continue regular back and core-strengthening exercises afterward, your back will progressively become stronger, and eventually you will conquer your pain.

Heel Raises

1. Practicing heel raises at home is a great way to relieve lower back pain. To perform this exercise correctly, stand upright with your back held straight and your feet at shoulder width. Slowly raise your heels as far up as you can while maintaining your balance on your toes. Then bring your heels back down. Continue to perform one to two sets of this exercise consistently to see improvement in your back.
   

   Wall Squats

2. Wall squats have been proven to help strengthen the muscles in your back as well as aiding in pain relief. To begin this exercise, stand upright with your back held straight and pressed firmly against a wall. Make sure your feet are at shoulder width. Now, walk your feet forward about 10 to 12 inches, taking small steps. Bend your knees and slide your back down the wall as you do so. Make sure your back doesn't bend and doesn't lose contact with the wall as you move forward. When your knees are bent 45 degrees, stop. Keep your abdominal muscles tight. Hold for about five seconds, and then slowly return to the starting position. Repeat this exercise 10 times.
   

   Standing Ball Exercise

3. This is an intermediate-level exercise, and should not be done if you are still a beginner. You need an exercise ball for this exercise.
   
   To begin, stand upright, exactly as suggested for the above exercise, except, this time there should be an exercise ball between your lower back and the wall. Slide your back down slowly as you walk your feet forward. Keep your abdominal muscles tight, and bend your knees anywhere between 45 to 90 degrees, stopping wherever you feel you can't bend them any further. Make sure your back does not release the pressure off the exercise ball. Now return to the starting position slowly.
   
   Repeat this 10 times. If you wish to make this more challenging, keep your arms raised over your head as you do this exercise.
