The Ab Coaster has been an integral part of the Steelers training regimen in 2008. The players and trainers all rave about the effectiveness and quality of the Ab Coaster abdominal workout.
I actually used the ab coaster at a gym. I was pretty impressed at how well it worked with a small amount of effort. I am used to grueling ab routines. This machine was fun and easy to use. It also seemed to be stretching me out as I did the routine.
