Borja Núñez, sports medicine physician: "It's impossible to cure low back pain if you don't feel well."

Borja Núñez warns that excessive sitting with poor posture can perpetuate lower back pain and frustrate any medical or physical therapy treatment. His video, which has become a benchmark among patients and professionals, insists that recovery depends on monitoring the way you sit daily.

The expert responds to a patient who confesses to continuing to experience pain despite prescribed exercises: "It's impossible to cure low back pain," he says, if the spine continues to be subjected to improper posture. For the doctor, the cause is often as simple as ignoring the natural anatomy of the lower back.

According to Núñez, spending long hours in the office without proper lumbar support puts the entire strain on the intervertebral discs and ligaments. This habit, repeated day after day , causes the tissues to sag and the discomfort to reappear.

Correct posture

The key, he explains, lies in maintaining stable lumbopelvic activation and respecting lumbar lordosis , the physiological curvature that protects the back. "If you don't feel well, it's very difficult to recover," the sports medicine specialist emphasizes.

Leaning back in a chair, crossing your legs, or slumping your shoulders relaxes the muscles that should support your bones. This seemingly harmless gesture shifts the load onto the ligamentous system, triggering a new episode of pain.

Núñez warns that the solution isn't to remain rigid, but to actively maintain the abdominal and lumbar areas . This slight stabilizing contraction reduces pressure on the discs and promotes internal healing.

Active musculature

The doctor points out that no stretching program will be effective if the patient neglects ergonomics at home or at work. The chair should be adjusted so that the hips and knees form a ninety-degree angle and the feet are flat on the floor.

It's also advisable to alternate periods of sitting with brief standing breaks to reactivate circulation and oxygenate the tissues. This simple adjustment, combined with manual therapy and controlled exercise, can accelerate improvement.

Ultimately, correcting the way you sit is an essential step to overcoming lower back pain. As Borja Núñez reminds us, "you have to change your position and adopt a correct posture ." A simple guideline can transform the quality of life for those who suffer from chronic back pain.
