It seems that those obsessed with abdominal
exercises are always looking at ways to increase the difficulty. If
you are one of those people, you can make the already difficult stability
ball crunch more challenging by adding the resistance from a band.Setting
up this exercise is pretty straightforward. All you have to do is anchor a
resistance band to a low point and set up the stability ball at a distance
that allows manageable abdominal crunches without pulling yourself off the
The most important thing to focus on when you're doing this exercise is to
make sure that the stability ball does not roll around on the floor. You are
taking advantage of the round surface, not it's ability to roll. This is
accomplished by using a manageable resistance and making sure to completely
stabilize yourself before you start the movement.
You can further increase the difficulty by allowing less of your back to be
in contact with the stability ball. These resistance band or tube stability ball
crunches can be performed at any time during your abdominal workout.
