Nothing beats relieving lower back pain than some well structured back pain exercises. If you work at a desk, you should also check that your chair is suitable and offers some degree of back support. Try out the tilting action of the back of the chair. Does it support your weight when you’re sitting up straight? Or does it tilt back too easily under your weight and prevent you from sitting straight? You want to be able to vary your position from rime to time by tilting back into a reclining position. But to reiterate, if the chair cannot support your weight and keep you at a 90-degree angle, the undesired tilting will cause you back pain.
To maximize your comfort, think of other constructive ways to vary your position when you’re sitting at a desk, try at least one back pain exercise each day, and try to get up and move about at least every 20 minutes.
