Title: Well-detailed crunch routine
Review: This is a routine of 10 basic crunches. The format is easy to follow - but as one reviewer states - one must get up and manually stop the disk to really get a full handle on each crunch - not very sexy, "fun", or hip - yet, the detailed narrative is precisely where this presentation has its strength - once the exercise is mastered, one can take it to the gym and elaborate - this production has noticeably improved my ab workout and my abs.
