Yeah that was the sort of thingI waslooking at. Realistically what would they help you achieve?
If you mean the stretching machines, the goal is help you achieve the side splits. Which is nice, but it's only one stretch....and not everyone is capable of it no matter how much they try. That's why I recommend Sang H. Kim's dvd &/or book on stretching for a more well-rounded stretching routine. It's much cheaper than the machine, too!
