i only do abs now as im bulking, i mix it up between bodyweight stuff (decline crunch, reverse crunches, blow up ball crunches, kettle bell ab stuff) and weighted (cable crunches are the best, then machines)
even during that pic (i puffed up a lil bit from bulkin) my cardio was just a little, i focused more on diet and liftin, and i was using ephedra-caffeine so that definitely helped.. but when i did cardio was take my EC right when i woke up, do 30 minutes low intensity (brisk walk or elliptical/bike) then had breakfast n other meals (carb cycle), n weights later in the day
