a small waist is a sign of fitness,discipline and healthy living imo,it looks great also.i never believed in using any type of resistance for the waist except bodyweight,people use weights for sit ups,crunches ect. i think thats a mistake,more resistance means bigger muscles and i dont want my waist bigger. keep the reps in the high numbers and just keep going higher and higher reps,dont add weight,who wants that bloated mentzer or colwman abs that r ripped but stick out as far as thier chests?not me
