Wicked back stretches with daddy

This is no joke, I've had a bad back for over 20 years. I've gone to numerous physical therapist plus a chronic pain clinic that was a six week Monday through Friday program. In my life I've had a discectomy, artificial disc surgery and spinal fusion in my lower back. These are the back stretches that I do every day in the morning and then the evening and by doing so my back remarkably remains relatively pain-free.
