My lower back would hurt from constant sitting and then I tried this and my pain just went away in 2 days. When I use it, I hang for 10 minutes in 5 min increments and level off each time before stepping off. Make sure you watch the DVD it come with. This machine really works and I never will live without one again. I feel my lower back "pop" when it needs too and that means that the discs are seperating from each other to let fluid through again. The pain is then gone if I had any. I swear by this machine and told all my family about it and now they even bought one for use. This machine pulls apart your spinal coard just like the day you were born to give you an almost brand new back. This is why people have been hanging from trees for centuries!!!
I will start out by saying I have one of the worst backs ever!! I needed to get some relief before my next shot and this was it. Now, I can just go hang upside (doesnt go all the way) down. The first time I got a bit of a head rush but the pay off was great. I went from being a hunched over granny to walking like Miss America. Pressure taken off of my discs and felt incredible. The material used to build this is great. I am very confident on it. Its very sturdy. Set up wasnt that bad although I did have my husband do it only because I dont trust myself!! The only downside is that if you are too tall.. you may bump your head. My husband is 6'4 I am 5'9. His head touched the floor when fully inverted. BTW, the chair doesnt invert 100% but its good enough to take the pressure off of my lumbar spline!!! All in all a great purchase!
