what is that ab machine.?!

Question: the machine that you do 12 crunches to the right and 12 crunches to the left what is the web site to it. and is it a good machine or a waste of money?
It's a waste of money. I say that because you don't put much weight behind your crunches. You should be able to crunch your own weight to get the most effect out of them. Otherwise what's the point. Put a mat on the floor and your feet under your couch. Cheapest way to go, and I have great abs.
