red ab machine

Has anyone tried this out, i have neck and back problems so  looking for something that will strengthen my abs and not put stress on those areas. Im not looking to have rock hard abs or to lose weight  just to tone up. any adice would be great. -christina

anything workout idea that you would think would be benificial would be great, im not very toned and would like to be.

I thought  the red looked hard to do since you have to keep your legs held off the ground to use it. That would take alot of strength that I just dont have yet. I bought the Ab doer and I love it. It has a bar abd a roller that supports your back while you use it.
