What Sitting Still for Hours Does to Your Hips

What the body does: hours seated in a fixed position, one foot on a pedal, both hands forward, spine unsupported at the low back, vibration throughout.

Where it shows up: low back, hips, neck and upper back, right leg and hip.

Why it happens: professional drivers show among the highest rates of musculoskeletal complaints of any occupational group. Sustained seated posture shortens hip flexors and unloads the glutes; whole-body vibration adds a low-level constant load; and the pedal-side hip works asymmetrically for the entire drive.
