Alright, so I'm naturally on the leaner side. 5'8 152 lbs, dont know my body fat percentage. I feel my abs are not nearly as good as they should be compared to the rest of my body. I eat very clean. 99% fat free ground turkey, chicken with all the fat cut off, and 93% lean beef, and tilapia, broccoli, apples, bananas, zucchini, yellow squash, and cucumbers. I have a moderate carb intake, very little to no carbs after 7.
I usually do weighted rope crunches, hanging knee raises front/side, and do decline sit ups with a 20 lbs weight but hold it when I'm flat (I guess a reverse weighted plank?) I don't do cardio, but I do skateboard about 1-2x week.
My question is, would cardio really help my abs show a lot more or would you say it is my routine.Â
