If you need any advice about clf and having a bad back, none of these people here can help you. I fell 50 and broke my back in 3 places, shattering one vertebrae to powder. I live with the pain and fought back from being paralyzed from the waist down and i'm still practicing clf. If you have any questions in regards to dealing with a back problem and clf, come send me a private message and we can talk about it. I have first hand experience beyond what anyone here can offer you.
