First, it is important to address the areas causing the movement compensation. As was mentioned previously, the low back muscles are rarely the cause of the problem. Therefore, rolling the muscles that make up the hip flexors, the glutes, and the calves can reduce the amount of tension in the low back.
Next, the low back can benefit from some much less dangerous types of therapy. Always consider working with a licensed therapist, no tool can target a muscle like a pair of experienced hands, especially in the low back.
