Yes: Spinal stenosis symptoms arise from pressure on the spinal nerves from spinal canal narrowing. Flexion exercises of the lumbar spine may help decompress the pressure and reduce symptoms. Core and spinal extensor exercises may help build up muscles that support the spine.

Yes: Exercises emphasizing a decrease in the sway of your back or lordosis and what are called williams flexion exercises may help. About 15% get worse, 15% get better over time and the rest remain the same.

Try planks: Planks are an exercise move that can strengthen the core while maintaining a neutral spine. You can perform this by getting into a push up position and holding this position or get on your elbows while keeping your belly off of the floor.

Not really: Exercise is in general is good, but it really does not do much for the condition of spinal stenosis. Somewhat similar in thought process to exercise not really doing a lot for a severely arthritic knee.
