Pain in the low back is frequently the result of a low level of muscle strength or lack of use. Having a strong core, which includes your lower back and abdominals, will often minimize lower back pain. Beginning an exercise program that engages your abdominals and lower back will help strengthen these muscles. Walking, running, aerobics, swimming and boxing are all cardio activities that engage these muscles. Yoga and pilates moves are great for lower back and abdominal training. There are many yoga and pilates DVD workouts currently on the market. Some are designed specifically to strengthen the lower back.
