Which are two common modifications for clients with lower back pain?

Choosing to avoid flexion-based exercises and maintaining a neutral spine is a well-established approach for clients experiencing lower back pain. Flexion can often exacerbate discomfort for individuals with back issues, as it places additional strain on the lumbar spine and engages the muscles in a way that may lead to further irritation or injury. By focusing on exercises that promote a neutral spine, clients can strengthen their core and support musculature without compromising the lower back. This method helps to stabilize the spine while allowing for safe movement patterns, ultimately garnering more benefits and less risk of pain during physical activity.

In contrast, the other options introduce elements that could potentially worsen lower back pain. Increased flexibility training and weights may not provide the stabilization needed for clients' spines, while emphasizing aerobic exercises with high impact and incorporating agility drills or plyometrics can further destabilize the back, posing risks of injury.
