For those who are lucky enough to have great abdominal strength or have
trained so that you find
stability ball crunches getting easy, you can make it tougher by adding
some resistance in the form of a cable pulley with rope attachment. Abdominal
exercises with added resistance have always been a favorite exercise among
bodybuilders who want to get that ripped six pack
abdominal look.
Since most exercises for the abdominals, which consist predominantly of
type-I slow twitch muscle fibers are done in sets with high reps,
extra resistance can help hypertrphy (make bigger) the abdominal muscle. The
larger the muscle, the more predominant will the ripped look provided body fat
percentage is low enough. Even if body fat percentage is not as low as
you would like, abdominal exercises with resistance such as these stability ball
cable rope crunches can help your abs be visible at higher levels of body fat.
