In its simplest form, inversion therapy is basically hanging upside down. If you are a yoga fan, doing inversions without the help of chairs and tables might be easier than singing your ABC's.
However, most people require a little (read a lot) help with balance, and inversion tables come in handy. It is worth mentioning that being inverted is not only for people with back pains- it has more than a dozen benefits for the entire body. These include improved brain function, blood circulation, a better immune system and the general well-being of the body.
