I used to have one of these years ago, but I don't remember the position to be in. It basically just supported the crunches. Mine had a video with it. Look on ebay, maybe you can get just the video from somebody.
yes you could also do a search and see how you work the darn thing lol!! I had somesort of ab bar thingy but it wasnt the roller, is that the one that you need to be on your hands and knees and you slide forward and back?
