Strengthening the lower back can be the first defense in fighting or preventing lower back pain. This is a great beginning exercise to strengthen your lower back.

Lay down on your stomach with your legs straight and your hands and arms stretched above your head. Simultaneously raise your right arm and left leg off the ground keeping the limbs totally straight. As you raise your arms and legs, concentrate on using your lower back to control the movement (you should feel a small contraction). After a small pause, lower to the ground. Again, concentrate on the lower back controlling the movement. It should take 3-4 seconds to complete one repetition. First do the right arm and left leg and then the left arm and right leg. Begin with 2 sets of 12-15 repetitions. Progress to 2 sets of 18-20 repetitions and then 3 sets of 18-20 repetitions.
