Simply bending over is a surprisingly common cause of back injury and pain. It often occurs when someone bends at the waist and hips instead of bending the knees to lower the body.
To increase stability and minimize straining your back when you bend down, be sure to keep your head right above your feet (not forward of your feet). Keep your back as erect as possible and centered over your hips and feet and squat down rather than bend forward. When bending down, don’t twist your body.
