I can sympathize with anyone suffering with lower back pain. I have spondylolisthesis of my L5/S1 (grade 2). There isn't a day that goes by in the last, oh say...15-20 years, that I haven't experienced low back pain to some degree. I wake up each and every morning with a very stiff, tight lower back. I do stretches while still in my bed (knee to chest, hamstring, child's pose) just so that I can stand up straight. Then I head straight to my inversion table and hang for 6-8 minutes to decompress my spine, before finally making my way downstairs (stairs are very tough on me first thing in the morning) to start my day. After my gym workouts, I literally spend about 30-40 minutes just on stretching alone...otherwise, my back and hamstrings will get all tight and spastic for the rest of the day. During longer rides, I have to take frequent rest breaks to get off the bike and stretch my back and legs. It sucks to live with back pain everyday.
