As others have suggested, I would recommend swimming. A stationary bike would be helpful for cardio, but lacking in core strengthening. Have you attempted a jogging regimen? If you're younger and have an annular tear, it may lead to worsened discogenic pain, otherwise I would give it a try. The benefits will take some time. Last, I would definitely do Pilates and/or Yoga. Your primary goal is to get your core strength increased to create a reduction of pressure on the discs (which Yoga and Pilates will do). Obviously, there are certain moves with these that common sense would tell you to avoid. Last, McKenzie exercises are specific for increasing core strength for low back pain. Don't do them if you have substantial stenosis or a spondylolisthesis, however.
