The Roller Coaster Crunch

The Roller Coaster crunch is an exercise for the abdominal muscles with a pair of apparatus we call the carriage and bench.

At first it might seem as though crunches on our apparatus would be the same as crunches on an Ab Wheel or Ab Dolly, or one of the many variations of these apparatus. However, crunches on these apparatus are uncomfortable. If a piece of equipment makes your body feel awkward or uncomfortable, then you won’t use it very long. This is why so many Ab Wheels and Ab Dolly’s end up on Craigslist or in the free pile.

With our apparatus, the upper body is higher than the lower body. This changes the biomechanics. Crunches on are apparatus are comfortable and sustainable over the long term.
