Normal. Lumbar lordosis simply means the normal backward curve of the low back. It is not an injury.
Otherway. Typically herniated disk can contribute to exaggerated lordosis.
Can I hit the gym? I have lumbar lordosis with a mild disc bulge and what exercises can I do in the gym.
Low back pain. Isometric exercises that strength core muscle groups are the best. Try working with a personal trainer to help avoid further injury. Common sense will dictate that if a particular exercise makes the pain worse then discontinue that aspect of the exercise program.
Muscle spasm. The most common reason you will hear the term.
