Isolating a specific muscle for strengthening, gaining joint mobility, or using hands-on therapy to reduce back pain won't help for long unless you also develop a healthy relationship with your body while you're at it. We haven't fully recovered if we go about our lives living in fear of pain or re-injury.
Unfortunately, we live in a culture that monetizes unhealthy beliefs about our bodies. So many people with back pain believe that they have to be so careful with their backs that it actually sets them up for more pain and injury down the road. We often think about injury and wear and tear as if we were automobiles-- once something is broken or starts to break down, that's it for us. This couldn't be further from the truth.
Our bodies are living, organic, and resilient structures with an exceptional capacity for healing and recovery. Spines aren't delicate; they are robust and adapt to the loads and stresses we put them under. Avoiding stress on our backs is what really causes them to become susceptible to pain and re-injury, and keeps us from getting better when we are actually hurt.
Come back from your back injury by getting stronger and more resilient than ever before. Bend and twist with confidence. Test your limits and challenge yourself a little from time to time; even if you have 'bone on bone' findings, fractured a vertebrae, or herniated a disc. Challenging ourselves is the healthy thing to do once the acute stage of healing is over. Focus on what feels good and develop confidence in lifting, carrying, and doing whatever else life requires of your body. Your back with love you back.
