I put this in the "beginners" because I know that the whole "six pack" topic usually is a question that noobs post too often about.
I lift 4 times a week, each workout is a different part (upper body + biceps, triceps and legs, Back...) Do cardio and abs on the same day, twice a week. I been doing this for about 6 months. So yea I am still new.
My diet is paleo-ish. Meaning I strive to have a paleo diet but have not really followed it strictly. I still drink milk and sparingly eat bread products, if I cannot avoid them. I am pretty much on a low carb diet.
I am 5'8' and 161 pounds. My goal is to eventually get up to 173-ish.
So my question is that sometimes I see my abs but most times I don't. Usually it is just having to do with lighting in the room. In my bathroom for example I see my abs in the mirror. But outdoors in natural sunlight, or in well lit rooms I don't. Now my bathroom is not dark persay, but the lighting does create the illusion of contours and shadow. I don't see a ripped six pack, but I still see a six pack that a skinny dude would see.
I figure that my issue is either that genetically I do not have very prominent abs or that I still have too much body fat.
I have been hearing that my upper back is weak and that might be related to why my abs are not showing. What I heard is that the upper back muscles when underdeveloped limits how much muscle you put on as well as your posture. I don't doubt that it is true, but there can be more factors. Such as the fact that I cannot really tell which individual "packs" are which. There is a line right at the top of my core on my ribs, but there is a slightly slightly noticeable line across my bellybutton below my middle line. I don't know if I am seeing things or is that lowest line really there and is under some fat layer. Is there a way I can find out for sure.
