hey, well u dont wanna over do it there...i mean if ur gonna do the crunches and tredmill then i would say alternate, do the crunches every other day and the day u dont do them then do the tredmill...and w/ the weight thing, my friend said that helps alot 2 and she did it and i think she has a six pack...and water is good for u, i never use 2 drink it but now itz all i drink, and if u cut down on soda and eat half of what u normally do then i think u will lose weight, also eat healthy, eat at least 2 fruits a day. and u wanna loose ur overall body fat first cuz u could do 1000 crunches and get nice abs but u wouldnt be able to see them cuz the flab...so if u do cardiac exercises then that will help to lose body fat and then u can do the crunches 2 tone ur stomach...hope i helped
