Which of the following is a recommended lifestyle modification to prevent back pain?

Maintaining a healthy weight is a crucial lifestyle modification for preventing back pain. Excess body weight can place additional stress on the spine, leading to discomfort and increasing the risk of injury. A healthy weight helps to ensure that the musculoskeletal system functions correctly and that the spine is supported adequately. Additionally, maintaining a healthy weight often correlates with overall fitness, which can enhance muscle strength and flexibility, further supporting spinal health and reducing the likelihood of back pain.

In contrast, other choices such as increased sedentary behavior or decreased mobility can weaken muscles and lead to stiffness, while excessive weight lifting, especially without proper technique, can strain the back and increase the risk of injury. Thus, maintaining a healthy weight stands out as a proactive measure for back pain prevention.
