I've been wondering, sometimes I have the great abs I want, sometimes they're not as good as I want them. This happens the same day. It's not because I'm undecisive about how I'd like my to look like, it's because when I look myself in the mirror, different times of the day and under different lighting my abs look different. So I cannot really tell if my abs are great or not because they are much different under different surroundings, enviroment and most important light (especially when coming from a lightbulb). Anyone had this similar issues or maybe some comments on this. I think the lightbulb from some angle throws some shadows on the abs so you can see the lines of your abdominal muscles better and give you a better impression.
