I am working at an office, sitting all day long. I think this is the reason why I feel lower back pain almost daily. I don't have time to go to physiotherapy, so I looked around to see what can I find a "home remedy". I found a method called inversion therapy which would help to decompress my spine. I also found a site where they review a few brands, the most recommended one was the Teeter 560. What do you think? Which is the best brand? Should I buy the Teeter 560?
