Re: lower back pain/tight hamstrings??
Bruce, if you haven't seen a doctor for your back pain in l0 years, I would suggest making an appt. to be evaluated. Indeed, tight hamstrings could be contributing but so could the exercises you are doing. If you have a bulging disc, there are some exercises that can make it worse. First, see the doctor, preferably an ortho or neurosurgeon, have an MRI and then discuss your options for pain relief with the doctor. Good luck.
