Crunches can be performed a number of ways and can often ressult in neck injury. A painful experience can be enough to discourage you for ever, so don t take a chance and get your CUATROMat; your progress will be faster, and while you become more and more agile and flexible with CUATROMat, more your crunches will be effective.
