What region of spine gets most stress?

The lumbar region of the spine, located in the lower back, typically experiences the most stress. This area bears the weight of the upper body and is involved in various movements, making it susceptible to strain and injury. Factors such as poor posture, heavy lifting, and prolonged sitting can exacerbate stress on the lumbar spine, leading to discomfort and chronic pain. Proper ergonomics and strengthening exercises can help alleviate this stress.
