Lumbar Disease

Any one out there with Lumbar disease?  I visit my chiropractor monthly for adjustments and it helps me quite a bit.  I walk as much as time or weather allows.  I have sedentary exercises to do when I get up in the morning. I am looking for easy lumbar strengthing exercises that will not kill my back the next day.  I am 58 years old so I need something that is appropriate for my age.

I have a disk that's completely gone waay down there. My chiropractor who knows sports therapy and my physical therapist have done wonders for me.  I can run in moderation now!   Reply if you would like more info on what has helped me, it's changed my life!
