The lower back bears about 60% of the weight of the upper body and is a vital support structure. Modern lifestyles are quietly "killing" our lumbar spines. A research team conducted a three-year follow-up study of 2,500 middle-aged and elderly people and found that static load is the leading cause of lower back problems.

Static load refers to the continuous pressure on the lumbar spine caused by maintaining the same posture for a long time. Although this pressure is not as immediate as acute injury, it is like "boiling a frog in warm water," damaging the health of the lumbar spine without being noticed.

Studies have found that 43.7% of lower back problems in daily life stem from poor posture, rather than what people usually think of as "lifting heavy objects" or "sudden sprains." When a person maintains poor posture for a long time, the pressure on the lumbar spine can be up to 1.4 times that when standing. If you add forward leaning or hunching, this figure can even reach 2.3 times! It's like constantly piling bricks on the lumbar spine until it can't bear the weight anymore.

Chronic fatigue injury is the hidden killer of lower back problems. It's like a rubber band; stretching it occasionally is fine, but if it's stretched for a long time, its elasticity will gradually weaken until it breaks.

What is the best way to maintain a healthy lower back? The answer is: scientific training of the core muscles combined with proper daily posture management. These two complement each other and are indispensable.
