The Roller Coaster Crunch

The Roller Coaster crunch is an exercise for the abdominal muscles.

At first it might seem as though crunches on our apparatus are the same as crunches on an Ab Wheel or Ab Dolly. However, with our apparatus, the upper body is raised to a higher elevation than the lower body. Raising the upper body changes the biomechanics of the movement. You might not be able to appreciate it just by looking at a picture, but when you try our apparatus in real life, we are confident you will agree that elevating the upper body makes the exercise more comfortable.
