it may
to tell you the truth they may, i personally know that some dont do crap, the ones like the "ab rocker" and "ab roller" are bull (they are like guided crunches "so each crunch is perfect"). I used one for 4 weeks (with about 6% body fat) and didnt see any results what so ever. I got an awesome burning feeling in my abs, but no results.
other abs machines may work, but i doubt they will work any better than a good "diverse" ab workout. so i wouldnt waste my money or time on one and then find out a month later that i got no results. thats just from what i know. i think the only product worth buying for abs is an exercise ball.
what i would like to know is why ab mahcines dont work, especially that one at the gym where u can load up weight and do crunches (its a mahcine).
