@hypertrophycoach: The only exercise you need for a six pack: ab mat crunches, according to Joe Bennett. If you are still doing 1,200 crunches every morning because that is how dad did it, the rectus abdominis is a muscle like every other and needs to be trained like one. For accessibility, efficacy, resistance profile and the ability to progress, a 15 to 20 dollar ab mat does the job about as well as any machine. Better looking abs come from lower body fat or bigger abs, nothing else. #abs #sixpack #abworkout #abmat
