I used the abslide machine and I returned it after a few days. I wouldn't say it was garbage, but it certainly wasn't worth the price to me. After I used it, I didn't feel anything in my stomach as much as in my back or arms, and my rear end was sore too. It does push you to do them though, it offers resistance. But I just couldn't see it working long term at all--the best results I have ever gotten for doing abs is tae-bo, and I'm going to stick with that forever. I don't think you should waste any money on an abslide, but that's just my opinion.
