I have got severe back pain due of herniated disc as result of overloading my spine in the gym.  My visits to chiropractors did not give me any relief. I started to use the Freespine fitness machine.  At the first training sessions I moved at the Freespine slowly within short and painless diapason of motions. From session to session the painless diapason of my motions was widened.  Within 4 weeks my back pain totally disappeared and I can bend my spine within its full diapason of motions without any pain. Now I regularly enjoy the Freespine fitness machine at home, keep my back flexible and strong and continue to pump the iron in the gym!
