Hi just posting to see if someone might recognize my problem and has a solution or good advise. My hamstrings are pretty tight, i have a bit of lordosis and had/ have a small hernia in my lower back. Since i started lifting everything has been pretty stable and as long as i dont play too much closed guard my lower back is usually fine. Now i started a new stretching regimen and think i would benefit a lot from also stretching my hamstrings, but everytime i do, my lower back gets inflamed.( not immediatly, but i will have some pain in the days following up the stretches).
