If your leg won't extend while sitting, it could be due to tight muscles, tendons, or ligaments, particularly around the hip or knee. Issues such as joint stiffness, injury, or conditions like Arthritis can also contribute to limited range of motion. Additionally, nerve compression or neurological conditions may affect muscle control. It's advisable to consult a healthcare professional for a proper diagnosis and treatment.

Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.
